The catalytic activity and durability are crucial for the development of high-performance electrocatalysts. To design electrocatalysts with excellent electroactivity and durability, the structure and composition are two important guiding principles. In this work, novel Pt/Ni(OH)2-NiOOH/Pd multi-walled hollow nanorod arrays (MHNRAs) are successfully synthesized. The unique MHNRAs provide fast tr...

Commercially grown, multi-walled carbon nanotubes (MWNTs), available in kilogramme quantities from three commercial suppliers have been characterised using a number of analytical techniques. The catalysts used in the growth of the MWNTs are identified by energy dispersive X-ray spectroscopy (EDX) and different growth mechanisms are postulated to explain the various structures present in the MWN...

Naturally occurring enzymes are truly remarkable catalysts. However, many are not suitable for practical synthetic chemistry because of poor substrate or product selectivity. This review highlights recent advances in engineering enzymes for selective catalysis. Selected topics include altering substrate specificity, altering substrate and product selectivity, engineering enzymes that catalyze c...

Multi-walled carbon nanotubes (MWCNTs) have been used in the oxidative dehydrogenation of 9,10-dihydroanthracene in an organic solvent (toluene) using molecular oxygen as the oxidant, and in the absence of trace amounts of metals. The process is very selective and almost no anthraquinone is formed. Thermal treatment of the MWCNTs at 2600 °C favors deoxygenation of the support and markedly impro...
