Breaking the trade-off between activity and selectivity has been a long-standing challenge in field of catalysis. We demonstrate importance disentangling target reaction from secondary reactions for case direct syngas conversion to light olefins by incorporating germanium-substituted AlPO-18 within framework metal oxide-zeolite (OXZEO) catalyst concept. The attenuated strength catalytically active Brønsted acid sites allows enhancing targeted carbon-carbon coupling ketene intermediates form...
Development of ammonia synthesis catalysts under mild conditions is highly desirable for carbon neutrality. Herein, we report that an iron-single-site catalyst confined within the graphene lattice derived from ball milling iron phthalocyanine with and promoted by alkali metal enables below 200 °C atmospheric pressure. It exhibits activity 1.1 μmolNH3 gc–1 h–1 at 150 10.3 190 °C, whereas no detected over a physical mixture graphene. X-ray absorption fine structure analysis 15N2–H2 periodic...
Oxide‐zeolite (OXZEO) catalyst design concept provides an alternative approach for the direct syngas‐to‐olefins (STO) with superior selectivity. Enhancing activity of oxide components remains a critical and long‐pursued target in this field. However, rational strategies optimizing oxides improving performance such complex reaction networks are still lacking. We employed energetic descriptors as adsorption energies CO* O* (GadCO* GadO*) through phase diagram (RPD) analysis to predict...

Recent theoretical studies predicted that the frustrated Lewis pair (FLP) formed by carbonaceous species confined in zeolites/zeotypes can activate H-H and C-H bonds. However, there still lacks experimental evidence understanding on role of FLP hydrogenation reaction. Herein, we combined experiments density functional theory (DFT) calculations to demonstrate Brønsted acid sites with weak strength transfer H+ form Si-O--Al as a base carbocation acid. They are electrostatically attracted...
Abstract Perovskite/silicon tandem solar cells (TSCs) have emerged as a highly promising technology for achieving exceptional power conversion efficiencies by leveraging the complementary light absorption properties of perovskite and silicon materials. However, electrical losses—originating from suboptimal film quality, pronounced nonradiative recombination at contact interfaces, charge transport inefficiencies in interconnecting layers (ICLs)—remain significant obstacles to reaching...
Despite the extensive studies on adsorption and activation of hydrogen over metal oxides, it remains a challenge to investigate structure-dependent its selectivity mechanism in hydrogenation reactions. Herein we take spinel solid solution MnGaOx with similar bulk chemical composition study reactivity syngas conversion. The results show that MnGaOx-Solid Solution (MnGaOx-SS) is typical Mn-doped hexagonal close-packed (HCP) Ga2O3 Ga-rich surface. Upon exposure hydrogen, Ga–H O–H species are...
Hierarchical zeolites have been demonstrated to be advantageous in catalysis and adsorption applications due facilitated diffusion without degrading its molecule sieving function. However, the direct synthesis of hierarchical one step is still challenging. Herein, we report a simple one-step single-crystalline by fractal growth induced strong heteroatom metal species on initially formed crystals. This method feasible presence variety (M–OH), which can develop stronger hydrogen bond with...
