The development of Pd-based materials with high activity and long-term stability is crucial for their practical applications as an anode catalyst in direct formic acid fuel cells. Herein, we reveal that the catalytic activity of Pd towards formic acid oxidation can be enhanced by incorporation of a series of rare-earth oxides, including ScO, CeO, LaO, and PrO. For example, Pd nanoparticles incorporated with ScO supported on nitrogen-doped reduced graphene oxide (Pd-ScO/N-rGO-, = 1/3, 1/2, 2/3, 1, and 3/2; "" denotes the molar ratio of Pd : Sc) can be obtained using a sodium borohydride reduction method.

Hydrogen peroxide (HO) production through photocatalytic O reduction reaction (ORR) is a mild and cost-efficient alternative to the anthraquinone oxidation strategy. Of note, singlet state oxygen (O) plays a crucial role in ORR. Herein, a hollow TiO@TpPa (TOTP) S-scheme heterojunction by the Schiff base reactions involving 1,3,5-triformylphloroglucinol (Tp) and paraphenylenediamine (Pa) for efficient photocatalytic HO production in deionized water has been developed.

The excessive consumption of sulfamethoxazole (SMX), a pharmaceutical antibiotic, poses significant environmental hazards. The FeS-persulfate (FeS-PS) system has been employed for SMX remediation because of its excellent performance. However, FeS tends to agglomerate and become passivated, negatively impacting its activation performance.

Structural diversity can affect the degradability of per- and polyfluoroalkyl substances (PFASs) during water treatment. Here, three PFASs with different functional groups-CF-R, PFHpA, PFHxS, and 6:2 FTS-were degraded using vacuum ultraviolet (VUV/UV)-based treatments. While fully fluorinated PFASs-PFHpA and PFHxS-were degraded faster in the VUV/UV/sulfite reaction than in VUV/UV photolysis, VUV/UV photolysis was more effective for degrading 6:2 FTS by OH radicals produced through photolysis of water.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.
