Advanced Science, EarlyView.A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Electrocatalytic Coupling Conversion of Methane by Dual‐Site Control in Nickel Oxyhydroxide
Advanced Science, EarlyView.Electrocatalytic coupling conversion of methane (CH4) is accomplished on the nickel oxyhydroxide (NiOOH), wherein the Ni─O dual‐site is triggered via the proper electronic interaction, synergistically promoting the C─H activation and C─C formation, enabling a selective and efficient C2 product generation route under ambient conditions. ABSTRACT Methane

One-pot synthesis of ordered mesoporous Ni-V-Al catalysts for CO methanation
, 2015 Preventing both the sintering of Ni particles and the coke formation in supported nickel (Ni) catalysts is a great challenge in catalysis. To address the problem, in this work, we have designed and synthesized a series of ternary Ni-V-Al metal oxide ...

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction
Advanced Science, EarlyView.Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Advanced Science, EarlyView.2D covalent organic frameworks are promising photocatalysts. Yet, precise synthesis of sub‐stoichiometric COFs remains challenging due to poor kinetic control. We propose a general strategy: tuning polymerization degree of kinetic intermediates via time or solvent polarity directs their thermodynamic repair into highly crystallization. Using [4+3]‐type
