The Special Issue of Nanomaterials "Ordered Mesoporous Nanomaterials" covers novel synthetic aspects of mesoporous materials and explores their use in diverse areas like drug delivery, photocatalysis, filtration or electrocatalysis. The range of materials tackled includes metals and alloys, aluminosilicates, silica, alumina and transition metal oxides. The variety of materials, synthetic approa...
The past several years has witnessed an exciting renaissance of the field organic electrosynthesis and electrocatalysis. As unconventional reaction tool with many unique features, electrochemistry enabled synthetic chemists to invent novel transformations, advance new strategies, improve sustainability synthesis. In this Guest Editorial, Song Lin Lutz Ackermann introduce special collection on E...
What Optical Electron-Transfer Reactions Can Teach Us about Electrode Kinetics and Electrocatalysisl
A number of ingredients are known or thought to be important in determining rates of electrochemical reactions and, therefore, mechanisms of electrocatalysis. These ingredients may include bond reorganization, solvent reorganization, electronic coupling, ion pairing, proton demand, 'work terms", and free-energy driving-force effects. Although evidence exists, in general, for a detectable role f...
Electrochemically active composite film containing multiwalled carbon nanotubes (MWCNTs) and vitamin B(12) was synthesized on glassy carbon, gold, and indium tin oxide electrodes by the potentiodynamic method. The presence of MWCNTs in the composite film (MWCNT-B(12)) modified electrode mediates vitamin B(12)'s redox reaction, whereas vitamin B(12)'s redox reaction does not occur at bare electr...
The future of analytical devices, namely (bio)sensors, which are currently impacting our everyday life, relies on several metrics such as low cost, high sensitivity, good selectivity, rapid response, real-time monitoring, high-throughput, easy-to-make and easy-to-handle properties. Fortunately, they can be readily fulfilled by electrochemical methods. For decades, electrochemical sensors and bi...
Highly ordered, and conductive inverse opal arrays were made with silica and subsequently coated with tin-doped indium oxide (ITO) via atomic layer deposition (ALD). We demonstrate the utility of the resulting mesostructured electrodes by further coating them with nickel oxide via ALD. The NiO-coated arrays are capable of efficiently electrochemically evolving oxygen from water. These modular, ...
