The potential for photosynthesis in hydrothermal vents: a new avenue for life in the Universe?

open access: yes, 2013
We perform a quantitative assessment for the potential for photosynthesis in hydrothermal vents in the deep ocean. The photosynthetically active radiation in this case is from geothermal origin: the infrared thermal radiation emitted by hot water, at ...

Bias‐Free Solar Upcycling of Nitrate and Glycerol with Highly Efficient and Durable Organic Semiconductor‐Based Photoelectrodes

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical (PEC) upcycling system integrating bi‐functional nickel‐iron‐phosphorus (Ni‐Fe‐P) catalysts with organic semiconductor (OS)‐based dual photoelectrodes is reported. The system enables simultaneous solar‐driven conversion of nitrate to ammonia and glycerol to formic acid with high efficiency and stability.

Genetic Surfaceome E. coli Reprogramming Enables Selective Water Oxidation

open access: yesAdvanced Materials, EarlyView.
A novel enzymatic material based on bilirubin oxidase (BOD) surface‐expressed on E. coli for effective electrocatalysis is reported. With this material, highly efficient and selective water oxidation is achieved, a critical half reaction for synthetic photosynthesis. Abstract Programming catalytic behavior at the microbial genome level is a frontier in

Plasmonic MoO3−x/Ag Photocatalyst for the Fixation of N2 from Air with the Solar Energy Conversion Efficiency Reaching over 0.28%

open access: yesAdvanced Materials, EarlyView.
A plasmonic MoO3−x/Ag photocatalyst is designed for efficient N2 photofixation. It exhibits superior light absorption, a Schottky‐barrier‐free feature, and plasmonic photothermal conversion. A diphase reaction platform is designed by loading the photocatalyst in a polymer film to suppress the light absorption of water and accelerate the mass transfer ...

Decoupling of Carrier Pathways in Au/Cu‐Zn3In2S6 Through Bulk Hole Trapping and Surface Hot Electron Accumulation Enhances Photocatalytic Hydrogen Peroxide Production

open access: yesAdvanced Materials, EarlyView.
We design and implement Au‐Cu co‐modified Zn3In2S6 catalyst with spatially decoupling charge carriers across bulk and surface sites, which effectively suppresses carrier recombination, drives surface hot electron accumulation and stabilizes intermediates for photocatalytic oxygen reduction. The optimized catalyst achieves an H2O2 evolution rate of 94.2
