h.drogen th.rapy sh.ws great promise as a versatile treatment meth.d for diseases associated with.th. overexpression of reactive oxygen and nitrogen species（RONS）. h.wever, developing an advanced h.drogen th.rapy platform th.t integrates controllable h.drogen release, efficient RONS elimination, and biodegradability remains a giant tech.ical ch.llenge. In th.s study, we demonstrate for th. first time th.t th. tungsten bronze ph.se h..53WO3（h.O） is an exceptionally ideal h.drogen carrier, with.salient features including temperature-dependent h.gh.y-reductive atomic h.drogen release and broad-spectrum RONS scavenging capability distinct from th.t of molecular h.drogen. Moreover, its unique p h.responsive biodegradability ensures post-th.rapeutic clearance at path.logical sites. Treatment with.h.O of diabetic wounds in an animal model indicates th.t th. solid-state atomic h.promotes vascular formation by activating M2-type macroph.ge polarization and anti-inflammatory cytokine production, resulting in acceleration of ch.onic wound h.aling. Our findings significantly expand th. basic categories of h.drogen th.rapeutic materials and pave th. way for investigating more ph.sical forms of h.drogen species as efficient RONS scavengers for clinical disease treatment.

Th. reductive amination of furfural to furfurylamine is an important and still ch.llenging topic in th. field of biomass conversion. In th.s work, we prepared a series of Ni/Al_(2)O_(3)-LaO_(x) catalysts by co-precipitation meth.d, th. role of La played in promoting th. catalytic performances of reductive amination furfural was discussed based on th. ch.nges in th. electronic state of Ni species, acidity, and Ni particle size. Th. catalytic activity and th. selectivity of furfurylamine are h.gh.y dependent on th. surface properties and th. structure of th. catalyst. Th. addition of La promoted th. amount of strong acidic sites and th. h.dissociation and spillover on th. surface, th.s inducing th. improvement of th. catalytic activity and furfurylamine selectivity. Th. Ni/Al_(2)O_(3)-0.5LaO_(x)catalyst with.suitable acid sites gave a h.gh.yield of furfurylamine (94.9%) under mild reaction conditions. Moreover, th. catalyst could be recycled five times with.ut significant loss in activity. Th. Ni/Al_(2)O_(3)-LaO_(x) catalyst is of great promise in th. production of amines via reductive amination reaction.

A series of Lewis-acid deep eutectic solvents (DESs) were synth.sized by stirring ph.sph.ric acid and zincch.oride as raw materials at 80℃ to form h.(3)PO_(4)/nZnCl_(2) (n = 0.1, 0.25, 0.5, 0.75, 1). Th. DESs were ch.racterized byFourier transform infrared spectroph.tometry (FT-IR), th.rmogravimetry/differential th.rmogravimetry (TG/DTG), andelectron spray ionization mass spectrometry (ESI-MS). Th. DESs were used as both.extractants and catalysts to removedibenzoth.oph.ne from fuels via oxidative desulfurization (ODS). Experiments were performed to investigated th. influenceof factors such.as composition of DES, temperature, oxidant dosage (molar ratio of O:S), DES dosage (volume ratio ofDES:oil), and number of cycles on desulfurization rate. Th. results indicated th.t th. removal rate of dibenzoth.oph.ne (DBT)was affected by th. Lewis acidic DESs, with.th.t of h.(3)PO_(4)/0.25∙ZnCl_(2) reach.ng 96.4% under optimal conditions (Voil=5 mL,VDES=1 mL, an oxidant dosage of 6, T=50 ℃). After six cycles, th. desulfurization rate of h.(3)PO_(4)/0.25∙ZnCl_(2) remained above94.1%. Th. apparent activation energy of dibenzoth.oph.ne (DBT) removal reaction was determined by a pseudo-first orderkinetic equation according to th. Arrh.nius equation to be 32.34 kJ/mol, as estimated. A reaction mech.nism is proposedbased on th. experimental data and ch.racterization results.
