Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

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

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.

Using Methane to Support Renewables for Decarbonisation

Methane
The cost of “carbon net zero by year 2050” for the UK will be high, and this target date can only be achieved if the project is undertaken in a progressive and timely manner; otherwise, costs will escalate. The base power source behind the UK approach to

Kinetic‐Directed Thermodynamic Repair Enables the Synthesis of High‐Strain 2D Sub‐Stoichiometric COFs

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
