Efficient photocatalytic hydrogen production from formic acid on inexpensive and stable phosphide/Zn3In2S6 composite photocatalysts under mild conditions

Construction of NiPx/MoS2/NiS/CdS composite to promote photocatalytic H2 production from glucose solution

“…The energies at 855.35 and 873.14 eV are attributed to the peaks of Ni 2p 3/2 and Ni 2p 1/2 , while the other two peaks are the satellite peaks of Ni 2p. Additionally, the positions of P 2p 3/2 and P 2p 1/2 are observed and located at 129.18 and 132.91 eV (Figure 2F), which is consistent with the previous report 32 …”

“…22 There are six peaks about Ni 2p and metal Ni 0 (Figure 2E) 2F), which is consistent with the previous report. 32 As shown in Figures 3A and 4A, and S4, the morphology of CdS performs nanorod shape with smooth surface, and the size is in microscales. NiS shows dendritic form (Figure 3D), and MoS 2 is a hydrangea-like structure composed of many flakes (Figure 3G).…”

MoS2/Zn3In2S6 composite photocatalysts for enhancement of visible light-driven hydrogen production from formic acid

“…mal photocurrent response, and pure ZIS6 exhibits relatively low photocurrent intensity, which may be due to a rapid photogenerated electron-hole pair recombination rate. Furthermore, the weaker photocurrent response of ZIS6 may be partially attributed to the wide band gap of pure ZIS6 [58,59]. However, 0.5% MoS2/ZIS6 displays significantly a higher photocurrent intensity than that of pure ZIS6, resulting from the heterojunction interfaces formed between MoS2 and ZIS6.…”

Decomposition of Additive-Free Formic Acid Using a Pd/C Catalyst in Flow: Experimental and CFD Modelling Studies

“…Recently, the photocatalytic production of H 2 from formic acid has attracted great attention. Duan et al [17] investigated the efficient photocatalytic hydrogen production from formic acid on inexpensive and stable phosphide/Zn 3 In 2 S 6 (ZIS6) composite photocatalysts under mild conditions. Ni 2 P and MoP were used as co-catalysts and the results showed photocatalytic H 2 production rates of the optimised 1.5 wt.% Ni 2 P/ZIS6 (45.73 µmol•h −1 ) and 0.25 wt.% MoP/ZIS6 (92.69 µmol•h −1 ) were 3.5 times and 7.2 times higher than that of the pure ZIS6 (12.88 µmol•h −1 ), respectively.…”
