Low-temperature molten salt synthesis and catalytic mechanism of CoS₂/NC as an advanced bifunctional electrocatalyst

Abstract

The development of productive and sustainable bifunctional electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) plays an important role in the commercial evolution of metal-air batteries. In...

Preparation of Highly Active Catalyst CoS2/CdS and Its Mechanism of Photocatalytic H2 Evolution

“…The peak values of S 2p 3/2 and S 2p 1/2 are at 161.56 and 162.77 eV, respectively. The Co 2p peaks at 781.82 and 798.46 eV correspond to Co 2+ 2p 3/2 and Co 2+ 2p 1/2 of CoS 2 , while those at 778.76 and 793.67 eV to Co 3+ 2p 3/2 and Co 3+ 2p 1/2 of cobalt oxide and the two peaks at 785.75 and 802.00 eV are assignable to shake-up satellites (Figure d). , Notably, S 2p and Cd 3d peaks of CC-15 shift to high binding energies compared with CdS, which clearly points to a strong chemical interaction between CoS 2 and the mixed-phase CdS in the catalyst.…”

“…49 The peaks observed at 161.46 and 162.70 eV belong to S 2p 3/2 and S 2p 1/2 (Figure 3c), which are in accordance with the reported values of S eV are assignable to shake-up satellites (Figure 3d). 50,51 Notably, S 2p and Cd 3d peaks of CC-15 shift to high binding energies compared with CdS, which clearly points to a strong chemical interaction between CoS 2 and the mixed-phase CdS in the catalyst.…”
