In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

, 2000 Catalytic fixed-bed reactors are the most important type of reactor for the synthesis of largescale basic chemicals and intermediates. In these reactors, the reaction takes place in the form of a heterogeneously catalyzed gas reaction on the surface of catalysts that are arranged as a socalled fixed bed in the reactor.

Advanced Materials, EarlyView.Replacing CO2 with CO at the cathode and integrating a catholyte‐layer membrane electrode assembly transforms paired electrolysis into a stable platform for co‐producing ethylene and 2,5‐furandicarboxylic acid. Combined experimental and techno‐economic analyses identify carbon monoxide and 5‐hydroxymethylfurfural as the most compatible pairing ...

Design of Fixed Bed Catalytic Reactors
Chemical engineering, 1965 前報において, モデル反応管と比較することによって触媒反応装置の簡便設計法を提案した。本報の目的はその設計法の精度を確認することにある。ニッケル・珪藻土触媒上でベンゼンの水添反応を行なっている内径5cmの反応管内温度分布と反応率分布を測定した。さらに設計の基礎的なデータである反応速度と充填層内の伝熱特性値も測定された。簡便法によって算出された温度と反応率分布は実験データとよく一致した。

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
