Preparation of uniform gold nanoparticles of different quantity deposited on zinc oxide nanorods for photoelectrochemical water splitting

Ultrafine Co3O4 nanoparticles-engineered binary metal nitride nanorods with interfacial charge redistribution for enhanced water splitting

“…2f, the Co 3 O 4 NPs/Co-Zn nitride possesses a relative high BET specic surface area of 57.2 m 2 g −1 , which exceeds that of other earth-abundant transition metal-based electrocatalysts reported elsewhere ZnO/AuNP-30 with 10.5 m 2 g −1 , Co-FeOOH@Ir-Co(OH)F with 30 m 2 g −1 , and 1T-VS 2 @N with 47 m 2 g −1 . [50][51][52] It is also worth noting that all features of the obtained isotherm match well with the typical IUPAC type IV pattern with the existence of hysteresis loop, suggesting the existence of mesopores with the hybrid structure. Indeed, the pore size distribution in Fig.…”

A highly enhanced photoelectrochemical performance of BiVO4 photoanodes modified with CoPi groups by increasing energy band bending, accelerating hole separation and improving water oxidation kinetics

“…They must meet the requirements for application, such as a proper energy band structure, high visible light absorption, good chemical stability, low toxicity and low cost. 3 Based on the above requirements, several photoanode materials such as ZnO, 4–6 TiO 2 , 7 WO 3 , 8 Fe 2 O 3 , 9,10 and BiVO 4 (ref. 11–13) have become research hotspots.…”
