Competitive‐Reduction Chemistry on Ni‐Doped FeS2 Catalyst Reinforcing Acid‐Corrosion Resistance for Stable Hydrogen Evolution Reactions

“…[29][30][31] Particularly, chemical corrosion phenomenon in acid electrolyte commonly exists for transition metal sulfide catalysts through HER process, which causes structure damage or the release of H 2 S gas, resulting in poor HER durability. [32][33][34][35] To suppress chemical corrosion and enhance HER durability, some attempts have been made for transition metal sulfides catalysts, such as coating a carbon armor layer, [33] introducing anions (P, N, or Se) through substitution, [35][36][37][38][39][40] and doping metal ions, [41][42][43] as well as constructing heterostructure. [44][45][46][47] However, the strategies mentioned above usually suffered from complex procedures and harsh conditions.…”

Insights into the Effect of Sulfur Incorporation into Tungsten Diphosphide for Improved Hydrogen Evolution Reaction

“…As shown in Figure S20, the P 2p and W 4f peaks of S-WP 2 were slightly shifted positively compared with WP 2 , indicating that the successful introduction of sulfur with different electronegativities changed the electronic structure of WP 2 . From the core-level spectrum of S 2p, phosphating can induce partial 2H-WS 2 to transform into a 1T-WS 2 phase at a low level of sulfur doping, which is beneficial to increase the conductivity and increase the active sites, thereby enhancing the HER activity. , With the increase of the S content, the WS 2 in S-WP 2 -10 is dominated by the 2H-WS 2 phase, while the intrinsic activity of pristine 2H-WS 2 is relatively poor, so the HER performance decreases instead. This phenomenon is mainly due to the decomposition temperature of NaH 2 PO 2 ·H 2 O being higher than the evaporation temperature of sulfur powder, so the partial sulfurization reaction occurs preferentially to the phosphating reaction.…”

Phosphorus-modified two-dimensional graphdiyne (CnH2n−2)/ZnCdS forms S-scheme heterojunctions for photocatalytic hydrogen production

“…3(c). The peak at 134.45 eV is the phosphate or metal oxide generated by P under the high-temperature calcination, such as P–O bond 57 in PO X , and the peak at 133.2 eV is ascribed to the phosphorus doping and P–C bond constructed in the GDY material. 58,59 The presence of the P–C bond effectively explains the effective doping of phosphorus.…”
