Aqueous-phase tandem reactions, as a fundamental aspect of green chemistry, hold crucial position in the contemporary synthesis fine chemicals, wherein advancement high-performance heterogeneous catalysts remains formidable challenge. Herein, we report Pt1Con single-atom alloy (SAA) catalyst which Pt single atoms are immobilized onto surface Co nanoparticles through Pt–Co coordination. The SAA exhibits high chemoselectivity for aqueous-phase hydrogenation–rearrangement reaction furfural (FAL) to cyclopentanol (CPL) (yield: >93%, considering carbon loss), with TOF value 2257 h–1 (based on Pt). A joint investigation based dynamics, isotope-label tracing experiments, EPR, and situ FT-IR verifies five-step consecutive pathway formation CPL. Notably, during reaction, rapid exchange hydrogen would occur between activated species water solvent. Furthermore, molecule does not serve H-donor but is involved rearrangement side chain furan ring. Kinetic studies combined DFT calculations substantiate that interface sites effectively lower energy barrier cyclopentanone (CPO) hydrogenation step via facilitating activation adsorption carbonyl group, accounting largely enhanced catalytic behavior. This study sheds light highly efficient stable biomass upgrading aqueous phase.

Nitrobenzene (NB) as essential products and raw materials in industrial production is a highly toxic prevalent water pollutant that threatens human health eco-safety. Photocatalytic methods are widely applied the field of environmental remediation due to their unique photoexcited redox capacity, which provides great potential for photoreduction NB. Here, ultrafast detoxification NB were explored by establishing biohybrid photocatalytic system with mild biomineralization. It was discovered whole-cell hybrid developed biomineralization CdS nanoparticles on cell surface Shewanella oneidensis MR-1 (SW) exhibited high activity Strikingly, SW-CdS first-order rate constant (k) 1.1 h–1, 54 times higher than S. (metabolic reduction). Impressively, this achieved highest ever reached various nanoparticles. In addition, obtained showed toxicity even lower traditional reduction product (aniline) detoxification. Further analysis revealed biomineralized served main catalytical center contributed ultrahigh efficiency SW-CdS. This work provided simple, ultrafast, low-toxic method NB, would be promising application remediation.

ABSTRACT In this research, bimetallic CdNi nanoparticles encapsulated in a magnetic spent coffee ground (Fe 3 O 4 @COFF/CdNi) was synthesized as new nanocatalyst. The structural and chemical characteristics of Fe @COFF/CdNi were comprehensively investigated using various techniques, including FT‐IR, XRD, XPS, TEM, VSM, EDS, TGA, BET, ICP. Through XPS analysis, TEM images, EDS mapping, the presence nanoalloys conclusively established. exhibited remarkable catalytic activity for hydrogen generation from water iso ‐propanol clean sacrificial agent. high performance attributed to synergistic cooperative effect Cd Ni within nanoalloys. Interestingly, process performed situ generated reduce range nitrobenzenes simultaneously into corresponding anilines yields (93%–98%). hydrophilic facilitated its reusability over five runs. Using most abundant source, first time generation–reduction without demanding on external light sources or power supplies can be mentioned significant milestone field study.
