Effect of metal loading and Ce addition on biochar-supported Co catalysts for CO2 methanation

Biochar
CO2 hydrogenation to methane is an interesting topic that can result in CO2 mitigation, providing a solution for global warming. Using a sustainable catalyst in that process will be considered as a plus point that makes the whole system (material ...

Robust and Thermally Stable Silicone Aerogels with Hyperconnected Network via Kinetically Optimized Hyperbranched Silane Precursors

Advanced Science, EarlyView.
Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

Comparative Life Cycle Assessment and Costing of Biogas Direct Methanation and Water Scrubbing Upgrade

Chemical Engineering Transactions
Biogas CO2 content can be valorized directly through the methanation process without the need for a cleaning step. By integrating biogas production with a methanation system, a net increase in biomethane yield and productivity can be achieved while ...

Methane

Eos, Transactions American Geophysical Union, 1981
I was surprised to read (Eos, 62(32), 618, 1981) that a Caltech‐Gulf Research and Development Company gas emission monitoring study along the San Andreas rift zone has so far recorded no methane. The same story credits me with finding methane along the East Pacific Rise, in Tibet, and in other exotic locations.

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

Advanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

Advanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.
