Design principles for peroxidase-mimicking nanozymes

Nanozymes, enzyme-like catalytic nanomaterials, are considered to be the next generation of enzyme mimics because they not only overcome natural enzymes' intrinsic limitations, but also possess unique properties in comparison ...

Interdisciplinary interactions inspire new discovery

Following an interdisciplinary approach, researchers in Japan have found new catalysts using unique Heusler alloys. Most studies on catalysts have been conducted by researchers in chemistry. However, catalysts also relate ...

Edges and corners increase efficiency of catalytic converters

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY's X-ray source PETRA III. A team of scientists ...

Platform optimizes the design of new, tunable catalytic systems

In the late 1700s, a Scottish chemist named Elizabeth Fulhame discovered that certain chemical reactions occurred only in the presence of water and that, at the end of those reactions, the amount of water was not depleted. ...

New graphene-based catalysts for the energy industry

Researchers at the Universitat Jaume I in Spain have developed materials based on graphene that can catalyse reactions for the conversion and storage of energy. The technology patented by the UJI combines graphene and organometallic ...

Nanocatalysts improve processes for the petrochemical industry

With the goal of advancing the oil, mining and energy industries, as well as counteracting the emission of greenhouse gases, nanotechnologist Hector Barron Escobar designs more efficient and profitable nanomaterials.

How to look for a few good catalysts

Two key physical phenomena take place at the surfaces of materials: catalysis and wetting. A catalyst enhances the rate of chemical reactions; wetting refers to how liquids spread across a surface.

Multimetal nanoframes improve catalyst performance

A team of researchers has synthesized a highly active and durable class of electrocatalysts by exploiting the structural evolution of solid Pt-Ni bimetallic nanocrystals into porous cage-like structures or nanoframes. This ...
