Summary: Space charge transfer of heterostructures driven by the work-function-induced built-in field can regulate the electronic structure of catalysts and boost the catalytic activity. In this study, an epitaxial heterojunction catalyst of CoO/Mo2C with interfacial electron redistribution induced by work functions is constructed for overall water splitting via a top-down strategy. The CoO/Mo2C catalyst exhibits excellent hydrogen evolution reaction (HER) catalytic activity with low overpotential and stability, as well as outstanding performance in overall water splitting. This work provides a novel possibility of designing materials based on interfacial effects arising from the built-in field for application in other fields.

Summary: A novel CoNiP nanoclusters-decorated photocatalyst consisting of porous g-C3N4 (PCN) and CdS was developed for pure water splitting. The addition of CoNiP significantly improved the activities and durability of the PCN-CdS composite for photocatalytic water splitting, achieving a maximized photocatalytic H-2 evolution rate. The enhanced performance of PCN-CdS by CoNiP was attributed to extended light absorption, more exposed active sites, regulated electronic structure, accelerated electrons transfer, and more trapped electrons. The PCN-CdS-CoNiP composite also exhibited high stability due to the reinforced chemical connection between PCN and CoNiP.

Summary: A hierarchical Co3O4/P-C3N4/TiO2 photoanode with improved visible lights absorption and enhanced PEC performance was achieved by encapsulating 1-D TiO2 nanorod arrays with phosphorous doped graphitic carbon nitride (P-C3N4) and decorating them with highly dispersed 0-D Co3O4 nanodots. The matched energy band positions in the photoanode facilitate swift diffusion of photogenerated holes, while the short diffusion path in Co3O4 nanodots suppresses the accumulation of surface positive charge. This study presents a perspective for enhanced visible light response in Co3O4/P-C3N4/TiO2 heterostructural photoanode for photoelectrochemical water splitting.

Summary: In this study, CuAl layered double hydroxide (LDH) and polymeric carbon nitride (g-C3N4, GCNN) were assembled into novel 2D/2D CuAl-LDH/GCNN heterostructures for visible-light-driven water splitting. The heterostructures exhibited significantly enhanced H-2 evolution, with the optimal LDH loading of 0.2CuAl-LDH/GCNN showing a 32-fold increase compared to GCNN. Additionally, 0.2CuAl-LDH/GCNN generated 1.5 times more O-2 than GCNN. The improved photocatalytic performance was attributed to efficient charge separation at the heterojunction interface, enhanced utilization of longer-wavelength photons, and higher surface area for catalytic reactions.

The optimized composite, containing 15 wt% Fe2P, showed the highest activity with a hydrogen production rate 107 and 39 times higher than that of pristine g-C3N4 and P-doped g-C3N4 respectively. Furthermore, this noble-metal-free photocatalyst achieved a solar-to-hydrogen conversion efficiency of about 0.2%.

Summary: This study synthesized hydrophilic polypyrrole and graphitic carbon nitride decorated zinc oxide nanorod arrays as a photoanode, which exhibited enhanced performance and stability for photoelectrochemical water splitting. The modified g-C3N4 nanosheets broadened the light absorption range and suppressed the recombination of photogenerated charges, while the polypyrrole coating layer inhibited the dissolution and corrosion of zinc oxide nanorods and facilitated the separation and transfer of photogenerated charge carriers. The hydrophilic surface of the photoanode provided a large electrochemically active surface area for efficient charge/mass transfer.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
