MgO-Decorated Amino-Functionalized N‑Doped Mesoporous Carbon: A Robust Support for PdAu-Catalyzed Hydrogen Evolution from Formic Acid Lin Li (28817) Songtao Zhang (1964341) Chunfan Mu (25137455) Yue Chi (1438810) Biophysics Biochemistry Cell Biology Evolutionary Biology Environmental Sciences not elsewhere classified Chemical Sciences not elsewhere classified Ecology Biological Sciences not elsewhere classified Information Systems not elsewhere classified sustainable energy storage noble metal catalysts initial turnover frequency fad ), constructed enriched pd species clean energy applications catalyzed hydrogen evolution achieving complete conversion multicomponent support engineering formic acid dehydrogenation anchoring pdau nanoparticles 2 </ sub robust support efficient dehydrogenation work highlights scalable strategy optimized pdau mechanistic demands free pdau 37 times 298 k 1866 h Formic acid (FA) is a promising liquid hydrogen carrier for sustainable energy storage, but its efficient dehydrogenation under mild conditions requires advanced catalyst designs. Here, we design a multifunctional supported PdAu catalyst tailored to the mechanistic demands of formic acid dehydrogenation (FAD), constructed by anchoring PdAu nanoparticles (NPs) onto MgO-decorated, nitrogen-doped, and amino-functionalized mesoporous carbon microspheres (MgO-NMC-NH₂). Systematic characterization reveals MgO decoration introduces abundant surface basic sites, improves PdAu NP dispersion, and induces the formation of electron-enriched Pd species. The optimized PdAu/0.6MgO-NMC-NH₂ catalyst exhibits exceptional FAD performance at 298 K, achieving complete conversion with an initial turnover frequency of 1866 h^–1, 2.37 times as high as that of the MgO-free PdAu/NMC-NH₂. This work highlights the potential of multicomponent support engineering for boosting the performance of noble metal catalysts, offering a scalable strategy to advance FA as a viable hydrogen storage material for clean energy applications. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acs.langmuir.6c04194.s001 https://figshare.com/articles/journal_contribution/MgO-Decorated_Amino-Functionalized_N_Doped_Mesoporous_Carbon_A_Robust_Support_for_PdAu-Catalyzed_Hydrogen_Evolution_from_Formic_Acid/34024580 CC BY-NC 4.0
