The electrocatalytic nitrate reduction to hydroxylamine (NH2OH) is a challenging catalytic process that has gained significant attention. However, its performance hindered by the low selectivity of electrocatalysts. Here, intermetallic PtSn nanosheets with p–d orbital hybridization have been synthesized, which significantly enhances NH2OH. Faradaic efficiency NH2OH reaches maximum 82.83 ± 1.55% at −0.10 V versus reversible hydrogen electrode (vs RHE), and yield achieves 6.15 0.32 mmol h–1 mgcat–1 −0.25 vs RHE. Mechanistic studies reveal between p-block Sn d-block Pt effectively adsorption desorption boost electrochemical synthesis. Given their excellent in synthesis NH2OH, are utilized as cathode an alkaline-acid hybrid Zn–NO3– battery facilitate production achieving FE 80.42%.

The development of efficient electrochemical catalysts capable highly sensitive detection small molecules poses a significant challenge. Recent advancements in two-dimensional materials, such as palladium metallene (Pdene), have shown promising application prospects overcoming these challenges. Nevertheless, critical issues optimizing their activity and enhancing sensitivity selectivity for molecular remain unresolved. In this study, we synthesized lanthanum-doped bimetallenes (PdLa BMLs), which serve high-performance constructing flexible sensors with selective responses to isopropanol. This improvement is attributed the nonhomogeneous crystal structure Pdene substrate, which, enhanced by La doping, optimizes electronic active sites, resulting increased adsorption capacity (evidenced upward shift d-band center) reduced reaction energy barriers isopropanol oxidation (IOR). Our findings not only demonstrate that doping enhances thereby improving catalytic efficiency, but also broaden applications metallenes electrocatalytic detecting relevant health food industries.
