Dispersible CdS1−Se solid-solution nanocrystal photocatalysts: Photoinduced self-transformation synthesis and enhanced hydrogen-evolution activity

Incorporating Ni-Polyoxometalate into the S-Scheme Heterojunction to Accelerate Charge Separation and Resist Photocorrosion for Promoting Photocatalytic Activity and Stability

“…As shown in Figure i, by fitting the PL lifetime decay curves, we concluded that the average lifetime (τ av ) of pure CZS is 2.552 ns, which is higher than that of the CZSNi-70 composite material (0.245 ns) . The results confirm a significantly promoted separation and transfer of photogenerated charge carriers in the constructed S-scheme heterojunction photocatalysts, which would provide a positive effect on photocatalytic H 2 evolution performance . Moreover, the water contact angle results (Figure S7) indicate that the wettability of the heterojunction photocatalyst was promoted by the introduction of Ni 4 POM, which is conducive to its application in aqueous photocatalytic systems.…”

Synergistic effect of oxygen vacancies and Ni particles over the ZnWO4/CdS heterostructure for enhanced photocatalytic reduction and oxidation activities

“…[1][2][3][4][5] Photocatalytic H 2 production has been regarded as a brilliant tactical strategy to support sustainable energy systems because it is eco-friendly, storable, and economical. [6][7][8] Photocatalytic CO 2 reduction can not only generate solar fuels in an environmentally friendly way but can also consume waste CO 2 to promote carbon neutrality. 9,10 Tetracycline (TC), as a representative antibiotic agent, has been extensively released into natural water cycles and constitutes a serious threat to the environment and public health.…”
