Heterogenous Catalyst Chemical Elements TRIZ Cases
- Vertical Heterojunction Metal Catalyst for Hydrogen Spillover
A metal catalyst with a vertical heterojunction interface transfers hydrogen adsorbed on transition metal oxide to transition metal sulfide.
- Bimetallic Alloy Catalyst for Low-Temperature Ammonia Decomposition
Composite metal alloy nanoclusters on oxide supports decompose ammonia into hydrogen at temperatures below 500°C.
- Supported Solid-Phase Catalyst for Magnesium Sulfite Oxidation
Activated carbon-supported catalyst accelerates magnesium sulfite oxidation through dispersed metal components.
- Alumina Silica Titania Catalyst Support for Fischer-Tropsch Stability
Titanium dioxide coating on alumina-silica supports prevents rehydration and dissolution, extending catalyst lifetime in slurry bubble column reactors.
- Cerium Oxide Catalyst Methionine Production
A cerium oxide catalyst enables single-stage methionine synthesis from 3-(methylthio)propionaldehyde.
- Hydrotreating Catalyst Metal Ratio for Deactivation Resistance
Specific Group VIII to VIB metal ratios in hydrotreating catalysts reduce rapid deactivation from metal deposition and clogging.
