Pulsed corona-induced CO2 methanation

, 2015
CO2 methanation has been observed by application of pulsed corona discharges in a CO2 atmosphere over a deionized water film. At 46 kJ/L energy density, approximately 440 ppm CH4 has been observed at a production efficiency near 398 pmol/J.

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

Advanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Site‐Specific Molecular Engineering Redirects Radical Pathways for Selective Photocatalytic Coupling of Methane to C2+ Hydrocarbons

Angewandte Chemie, EarlyView.
Site‐specific self‐assembly of alkyl thiols on Au/TiO2 enables precise modulation of interfacial electron distribution and the local microenvironment through covalent Au‐thiolate interactions. This site‐specific molecular engineering synergistically promotes surface kinetics and charge separation, suppressing ·O2−‐driven overoxidation and thereby ...

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Energy Materials, EarlyView.
This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Olive stone-derived biochar as a sustainable catalyst support for CO2 methanation

Journal of CO2 Utilization
The hydrogenation of carbon dioxide (CO2) into methane presents a promising strategy for CO2 utilization. However, the large-scale implementation of this process remains limited by the lack of cost-effective and sustainable catalytic materials.

Farmers' Preferences for Fossil‐Free Mineral Nitrogen Fertilizers: Role of Prices, Climate, Production Origin, and Identity

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Disruptions in global fertilizer markets and climate targets have increased interest in fossil‐free mineral nitrogen fertilizers. This study examines farmers' preferences for conventional (fossil‐based) and fossil‐free fertilizers using a labeled discrete choice experiment with 211 Swedish farmers.

Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices

Agribusiness, EarlyView.
ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

3D-printed NiZr0.1/SiOC monolithic catalysts with synergistic Zr doping for enhanced low-temperature CO2 methanation: dual-pathway mechanism and structural stability

Fuel Processing Technology
Monolithic NiZr0.1/SiOC catalysts with tailored architectures were fabricated via direct ink writing (DIW) 3D printing for CO2 methanation. Zr doping markedly enhanced low-temperature activity (

Joule self‐heating enabled oxygen transport and coupled methane reactions in a La0.6Sr0.4Co0.2Fe0.8O3‐δ hollow fiber membrane reactor

AIChE Journal, EarlyView.
Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.
