Methane Emission Control

Johnson Matthey Technology Review, 2016
Natural gas is of increasing interest as an alternative fuel for vehicles and stationary engines that traditionally use gasoline and diesel fuels. Drivers for the adoption of natural gas include high abundance, lower price and reduced greenhouse gas emissions compared to other fossil fuels. Biogas is an option which could reduce such emissions further.

Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

Advanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct

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 ...

Greenhouse gas emissions from agriculture in the EU: A spatial assessment of sources and abatement costs [PDF]

Agriculture contributes significantly to the emissions of greenhouse gases in the EU. By using a farm-type, linear-programming based model of the European agricultural supply, we first assess the initial levels of methane and nitrous oxide emissions at ...

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 ...
