About this collection

Professor Shouheng Sun introduces this Editor’s Choice collection focusing on nanomaterials for catalysis.
“Nanoscale research has advanced to such a level that many different kinds of materials can now be prepared with precise control of the nanoscale dimensions and properties. This is especially visible in the field of catalysis. With this in mind, we have compiled a list of highly cited articles on the theme “nanomaterials for catalysis” (17 research articles and 3 review papers) to provide you, our readers, with a quick glance at this recent hot topic. 
Many of the papers featured in this collection discuss catalysis for reactions related to energy conversion and fuel generation. Nanocatalysts for these applications are often based on transition metal oxides/sulfides/nitrides, but a new nanomaterial, graphitic carbon nitride, seems to be especially attractive for photocatalysis, as highlighted in Wang et al. “Water-assisted production of honeycomb-like g-C3N4 with ultralong carrier lifetime and outstanding photocatalytic activity” and Qin et al., “Improving the photocatalytic hydrogen production of Ag/g-C3N4 nanocomposites by dye-sensitization under visible light irradiation.” Three review papers highlight the recent progress on graphene oxide-transition metal oxide composites, metal organic framework composites and a theoretical view of heterogeneous catalysis for CO2 reduction. With further advances in this hot area, we are confident that more and more exciting works will appear in Nanoscale. We hope that you find this compilation informative and useful.”
