Abstract Graphdiyne (GDY) is a new carbon allotrope with excellent properties due to its unique structure and highly conjugated system. In this work, GDY/CuMoO 4 (CMO)/CuO tandem S-scheme heterojunction was constructed using the cross-coupling method. Among them, CuI not only used as coupling catalyst obtain easily collected GDY, but also precursor for more active composite catalysts. 2D GDY provides substrate loading of CMO CuO, while system electrical conductivity allow composites form strong charge distribution transport. The step-by-step progressive heterojunctions based on one-step calcination strategy have stronger reducing activity carrier transfer capability. intrinsic mechanism investigated by photoelectrochemical characterization in situ x-ray photoelectron spectroscopy analysis, photocatalytic hydrogen production reaction proposed. This work viable approach development photocatalysis design heterojunctions.

The high cost and limited sources of fossil fuels led researchers to discover alternative energy. aim this work is explore stable efficient catalysts for hydrogen evolution under sunlight. From perspective, various including CdS, Ag@CdS, Cu@CdS, Cu/Ag@CdS have been designed synthesized via the hydrothermal method. To enhance surface stability activity copper silver metals were selected as cocatalysts. Cocatalyst contents in situ deposited over surfaces CdS using a chemical reduction approach. optical structural properties investigated UV–vis/diffuse reflectance spectroscopy (DRS), Raman, photoluminescence (PL), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), Fourier-transform infrared (FTIR), atomic force (AFM) techniques. Their compositions characteristics confirmed by energy-dispersive (EDX) photoelectron (XPS) studies. Thermal was assured thermogravimetric analysis (TGA), whereas magnetic determined paramagnetic (EPR). Photoreactions done quartz photoreactor (150 mL/Velp Scienific) generation activities monitored gas chromatographs, i.e., GC-TCD (Shimadzu-2010/Japan). results depict that with 2% Cu 1% Ag on exhibit highest (i.e., 18.93 mmol g–1 h–1 45.04% quantum efficiencies). higher attributed synergism generated between cocatalysts during photoreaction. It has predicted populations plasmon resonance (SPR) Cu/Ag Schottky junctions formed restrict charge recombination back reactions). Additionally, factors like pH, temperature, photocatalyst dosage, intensity light evaluated discussed optimize ideal conditions. study hold promise an eventual transition replace costly conventional used sustainable generation.

Photocatalytic water cracking hydrogen (H2) production is a promising clean energy technology. Therefore, ternary CdS@Nb2O5/Nb2CTx (MXene) heterojunction with hierarchical structure was designed to promote photocatalytic H2 evolution. When Na2S/Na2SO3 and lactic acid were used as sacrificial agents, the evolution reaction (HER) rates of optimized photocatalyst 1501.7 2715.8 μmol g-1 h-1, 12.4% 26.1% apparent quantum efficiencies (AQE) at 420 nm, respectively. Its HER performance 10.9-fold higher than that pure CdS remained 87% activity after five rounds cycle tests. Such an enhancement stems from excellent light absorption properties, tight interfacial contact, fast charge transfer channel, sufficient active sites. Mechanism analysis demonstrates S-scheme Schottky junction synchronous regulation boost for production. This work creates possibilities manufacturing Nb-based MXene photocatalysts converting solar other applications.
