“…Photocatalytic water splitting is an effective and attractive technology to convert solar energy into clean hydrogen energy. Since the pioneering work reported on TiO 2 electrode in 1972, 1 researchers have studied a series of catalysts ranging from metal oxides to other materials, such as metal sulfides, 2,3 non‐metal semiconductors (e.g., C 3 N 4 and graphene), 4,5 and complex catalysts 6–9 . As one of the important metal sulfides, CdS have attracted widely attention due to its relatively simple chemical structure, good light absorption and suitable band positions for photocatalytic redox reaction 10,11 .…”

“…Photothermal catalytic reduction of carbon dioxide by renewable hydrogen has recently emerged as a promising way of converting solar energy into chemical energy [1][2][3][4][5][6][7][8][9][10][11]. This pathway, often based on the photothermal effect of metal nanostructures, allows for much more effective utilization of photons from solar radiation, particularly low-energy infrared light that is often wasted in photochemical catalysis [12][13][14][15][16][17]. The first process of photothermal CO 2 catalysis is the light-to-heat conversion that occurs mainly on the catalyst.…”

Understanding the role of heat transfer between catalysts and substrates is important for enhancing photothermal CO 2 catalysis. Herein, we investigate the effect of different substrates, including silicon wafers, glass slides and copper plates, on the photothermal catalytic performance of commercial Ni catalysts. The highest CO 2 conversion rate and CO selectivity are observed in the catalyst film on the glass substrate, and this can be traced to a reduced catalyst-to-substrate heat transfer that increases the catalyst temperature under illumination. Our study reveals the important role of thermal management between catalysts and substrates in photothermal catalysis and sheds light on reactor design for efficient solar-to-chemical energy conversions.

To improve photoelectrochemical (PEC) water splitting, various ZnO nanostructures (nanorods (NRs), nanodiscs (NDs), NRs/NDs, and ZnO NRs decorated with gold nanoparticles) have been manufactured. The pure ZnO nanostructures have been synthesized using the successive ionic-layer adsorption and reaction (SILAR) combined with the chemical bath deposition (CBD) process at various deposition times. The structural, chemical composition, nanomorphological, and optical characteristics have been examined by various techniques. The SEM analysis shows that by varying the deposition time of CBD from 2 to 12 h, the morphology of ZnO nanostructures changed from NRs to NDs. All samples exhibit hexagonal phase wurtzite ZnO with polycrystalline nature and preferred orientation alongside (002). The crystallite size along (002) decreased from approximately 79 to 77 nm as deposition time increased from 2 to 12 h. The bandgap of ZnO NRs was tuned from 3.19 to 2.07 eV after optimizing the DC sputtering time of gold to 4 min. Via regulated time-dependent ZnO growth and Au sputtering time, the PEC performance of the nanostructures was optimized. Among the studied ZnO nanostructures, the highest photocurrent density (Jph) was obtained for the 2 h ZnO NRs. As compared with ZnO NRs, the Jph (7.7 mA/cm2) of 4 min Au/ZnO NRs is around 50 times greater. The maximum values of both IPCE and ABPE are 14.2% and 2.05% at 490 nm, which is closed to surface plasmon absorption for Au NPs. There are several essential approaches to improve PEC efficiency by including Au NPs into ZnO NRs, including increasing visible light absorption and minority carrier absorption, boosting photochemical stability, and accelerating electron transport from ZnO NRs to electrolyte carriers.
