A novel antimonotungstate (AT)-based heterometallic framework {[Er(H2O)6]2[Fe4(H2pdc)4(B-β-SbW9O33)2]}·50H2O (1, H2pdc = pyridine-2,5-dicarboxylic acid) was obtained through a synergistic strategy of in situ-generated transition-metal-encapsulated polyoxometalate (POM) building units and the substitution reaction. Its structural unit is composed tetra-FeIII-substituted Krebs-type [Fe4(H2pdc)4(B-β-SbW9O33)2]6– subunit two [Er(H2O)6]3+ cations. This can be regarded as product carboxylic oxygen atoms ligands replacing active water [Fe4(H2O)10(B-β-SbW9O33)2]6– species.

Light-driven direct conversion of methane to formic acid is a promising approach convert value-added chemicals and promote sustainability. However, this process remains challenging due the complex requirements for multiple protons electrons. Herein, we report design WO3-based photocatalysts modified with Pt active sites address challenge. We demonstrate that modulating dimensional effect on WO3 support key enhancing catalytic performance selective CH4-to-HCOOH conversion. The nanoparticles exhibit superior rate, selectivity durability in production HCOOH compared Pt-free sample decorated single atoms. optimal PtNPs-WO3 catalyst achieves rate 17.7 mmol g–1, 84% stability maintained up 48 h. Mechanistic studies show protonation O2 hydroxyl radicals limiting step yield. can facilitate electron transfer dissociation, generating via proton-coupled process. This provides sufficient lower formation barrier •OH radicals, thereby promoting activation CH4. In addition, regulate adsorption oxygenated hydrocarbon intermediates, increasing reaction. work advances our understanding effective regulation reaction pathways.

Methane is both a greenhouse gas and an abundant C1 fuel resource that exists in nature. The selective photocatalytic upgrading of methane into multicarbon (C2+) chemicals can mitigate the effect promote utilization value methane, which C–C coupling step key to production products. Achieving this targeted under ambient temperature pressure conditions requires efficient activation C–H bonds as well balancing adsorption desorption various free radicals intermediates facilitate coupling. In Review, we delve recent advances C2+ importance catalyst design, including active site assembly, crystal surface, valence reconstruction, first emphasized. Then, discuss how coreactants such carbon dioxide monoxide be introduced enhance chain growth pathways. Furthermore, also summarize developments looping systems photoelectrocatalysis. Finally, conclude with outlook for future advancement field. This Review aims provide general framework investigating reactions toward products, thereby suggesting research directions environmentally friendly strategies.
