Semiconductive Copper(I)–Organic Frameworks for Efficient Light-Driven Hydrogen Generation Without Additional Photosensitizers and Cocatalysts

Semiconductive Copper(I)–Organic Frameworks for Efficient Light‐Driven Hydrogen Generation Without Additional Photosensitizers and Cocatalysts

No additives required: A low-cost Cu2I2-based MOF exhibits efficient photocatalytic H2 production without additional photosensitizers and cocatalysts. DFT calculations reveal a good band alignment with the water redox energy levels. The proposed mechanism demonstrates that Cu2I2 clusters in Cu-I-bpy (bpy=4,4′-bipyridine) serve as photoelectron generators to accelerate copper(I) hydride interaction for hydrogen evolution.

Decoupling the Effects of High Crystallinity and Surface Area on the Photocatalytic Overall Water Splitting over β-Ga2O3 Nanoparticles by Chemical Vapor Synthesis

Decoupling the Effects of High Crystallinity and Surface Area on the Photocatalytic Overall Water Splitting over β‐Ga2O3 Nanoparticles by Chemical Vapor Synthesis

Conscious decoupling: Ga2O3 nanoparticles were synthesized by chemical vapor synthesis (CVS) at different temperatures and pressures. When loaded with Rh/CrOx co-catalysts all samples evolved H2 and O2 in the stoichiometric ratio of 2:1 in photocatalytic overall water splitting (OWS). The OWS activity of the CVS samples is demonstrated to depend on the optimum ratio of crystallinity and specific surface area.

Photocatalytic Overall Water Splitting over MIL-125(Ti) upon CoPi and Pt Co-catalyst Deposition

Photocatalytic Overall Water Splitting over MIL‐125(Ti) upon CoPi and Pt Co‐catalyst Deposition

Time to split: Photocatalytic overall water splitting is realized by taking advantage of the semiconductive and porous properties of MIL-125(Ti). CoPi and Pt are deposited into MIL-125(Ti) in two steps, and the as-prepared MIL-125(Ti)-CoPi-Pt produces stoichiometric H2 and O2 evolution from pure water with no external bias. The co-catalysts CoPi and Pt not only act as reactive sites for oxygen and hydrogen evolution, respectively, but also decrease the overpotential of O2 and H2 evolution from water and improve the photogenerated charge separation efficiency.
