Hydrogenation reactions are integral to hundreds of chemical manufacturing processes across agrochemistry, pharmaceuticals, industrial chemistry, and many other sectors, representing a combined market worth tens of billions of dollars. However, many currently used photocatalysts are unable to achieve the yields required for industrial-scale applications and suffer from limited selectivity\u2014struggling to steer chemical reactions toward the desired products.<\/p>\n
Moreover, these catalysts often require additional agents, such as magnesium for water activation, and their applicability is typically restricted to a narrow range of organic reactions. Developing new solutions that, unlike existing ones, can operate under low temperatures and pressures and without the use of gaseous hydrogen remains a major scientific and industrial challenge.<\/p>\n
One promising approach involves using water as a proton source in combination with suitable photocatalysts, enabling efficient transformation powered by solar energy.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” left_padding_desktop=”0″ constrain_group_2=”yes” right_padding_desktop=”0″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][image_with_animation image_url=”7046″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” border_radius=”10px” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][vc_column right_padding_desktop=”5%” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”advanced” gradient_type=”default”][vc_column_text]\n
\u201cIn developing a new type of photocatalyst, we combined expertise in nanotechnology and atomic engineering,\u201d said corresponding author Radek Zbo\u0159il. \u201cTogether with our international collaborators, we designed and synthesized a material consisting of palladium nanoparticles anchored within a two-dimensional carbon nitride matrix. Isolated palladium atoms in various oxidation states were incorporated in the vicinity of these nanoparticles. Thanks to the synergistic effect of the components, the new material managed to convert a broad range of organic compounds into desired products with exceptional yields and selectivities, paving the way for industrial applications.\u201d<\/p>\n
During the research, the team observed that the reaction yields increased dramatically when isolated palladium atoms in varying oxidation states were located near the nanoparticles.<\/p>\n
\u201cWe therefore intentionally designed a composite system in which isolated palladium atoms attracted photogenerated holes to oxidize water, while nanoparticles facilitated the transfer of hydrogen to unsaturated bonds in organic molecules. This is a unique concept that could revolutionize catalytic processes in organic chemistry,\u201d explained Giorgio Zoppellaro, who played a key role in elucidating the material\u2019s mechanism of action.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]The research teams from CATRIN and VSB-TUO, in collaboration with colleagues from Germany\u2019s Leibniz Institute for Catalysis, have been investigating hydrogenation reactions for years.
