Controlled Carbon Nitride Growth on Surfaces for Hydrogen Evolution Electrodes
Shalom, Menny; Gimenez, Sixto; Schipper, Florian; Herraiz Cardona, Isaac; Bisquert, Juan; Antonietti, Markus Wiley (2014-04-01)Efficient and low-cost electrocatalysts for the hydrogen evolution reaction are highly desired for future renewable energy systems. Described herein is the reduction of water to hydrogen using a metal-free carbon nitride ... -
The Complex Role of Carbon Nitride as a Sensitizer in Photoelectrochemical Cells
Herraiz Cardona, Isaac; Yang, Xiaofei; Gimenez, Sixto; Antonietti, Markus; Shalom, Menny; Xu, Jingsan Wiley (2015-08)The role of carbon nitride (C3N4) as an absorber in a photoelectrochemical cell is reported. C3N4-sensitized TiO2 mesoporous film created via in-situ, vapor-transport growth results in a direct Ti–O–C bonding. The material ... -
Toward Efficient Carbon Nitride Photoelectrochemical Cells: Understanding Charge Transfer Processes
Albero, Josep; Barea, Eva M; Xu, Jingsan; Mora-Sero, Ivan; García, Hermenegildo; Shalom, Menny Wiley (2016-06)Hole extraction is the key! Charge recombination, electron injection and hole extraction rates between C3N4, TiO2, and several electrolytes in a photoelectrode configuration are studied. It is found that the TiO2/C3N4 ...
