New modeling of 3D quaternary type BaCuZnS-graphene-TiO2 (BCZS-G-T) composite for photosonocatalytic hydrogen evolution with scavenger effect

Abstract

For the efficient evolution of hydrogen, we designed a 3D quaternary BaCuZnS-graphene-TiO2 (BCZS-G-T) composite with a quaternary material by an ultrasonic method.

Comparative and Efficient Ammonia Gas Sensing Study with Self-assembly-Synthesized Metal Oxide-SiC Fiber-Based Mesoporous SiO2 Composites

“…The downward change in the G band has been ascribed to the incomplete interaction of the metal particles, thus suggesting that the nanocrystals bond weakly to the carbon. These results suggest that the nanocomposite represented a channel for transporters and the prevailing electrical and charge-sharing properties. , …”

“…These results suggest that the nanocomposite represented a channel for transporters and the prevailing electrical and charge-sharing properties. 51,52 Figure 5 Figure 8 shows the ammonia gas sensing result of the In 2 O 3 −SiC−SiO 2 composite. From the CV data, it is apparent that the In 2 O 3 −SiC−SiO 2 sample exhibits constant current density results for 6 and 24 h treatment, and the current amount is around 0.8 mA cm −2 .…”

Novel Approach to Synthesis of AgZnS and TiO2 Decorated on Reduced Graphene Oxide Ternary Nanocomposite for Hydrogen Evolution Effect of Enhanced Synergetic Factors

“…These findings suggest that ultrasonic synthesis is an effective method to synthesize AgZnS nanoparticles. Due to their weakness, there were hardly any diffraction peaks of RGO to be found relative to the strong diffraction pattern of TiO 2 and AgZnS, which was possibly because of the low crystallinity and content of RGO in the prepared samples [ 28 ]. Raman and TEM data from subsequent research could establish the presence of GO in the composites.…”

“…As a good solid-state electron mediator, the combination of TiO 2 or TMS can prompt the rapid transfer of photo-generated electrons from the inorganic semiconductor to graphene, reducing the electron-hole recombination rate, which is necessary for achieving higher efficient photocatalytic hydrogen production. The result of the CV test proves that the AgZnS-G-T electrode has excellent electrocatalytic performance for HER [ 28 , 31 , 34 ].…”
