Special Issue Information

Dear Colleagues,

Electrocatalysis strongly relies on the intrinsic properties of materials, ranging from small organic molecules to metal/metal oxides, metal–organic frameworks, covalent–organic frameworks, carbon materials, polymers, etc. Emerging materials for novel electrochemical applications and their catalytic properties are the driving force behind the improved sensitivity, selectivity, and stability of such methods. Several materials have attracted the attention of researchers in the application of electrochemical biosensors, chemical sensors, and gas sensors. For example, metal–organic frameworks have been studied extensively for their gas absorption and desorption capabilities, due to their tunable pore size and modified groups allowing good selectivity. Metal/metal oxides have been used ubiquitously in various electrochemical applications for their good conductivity and for their role in improving measurements and sensing sensitivity in the liquid environment. MXenes (Mn+1AXn, where M is any early transition metal, A is an element from group 13 or 14 of the periodic table, and X is C or N, n=1-4) have been identified and applied by a great number of researchers in various electrochemical applications for energy storage, photocatalysis, gas sensing, and water desalinization. This Special Issue focuses on novel or recently available materials with regard to their electrochemical applications in electrocatalysis. Authors are encouraged to contact the editor with their intention to submit, in order to ensure the paper lies within the scope of the Special Issue.

The determination of pH is of paramount importance in environmental, pharmaceutical, and medicinal sciences, etc., for accurate controlling, monitoring, and adjusting whole processes on microscale and macroscale. Therefore, the pH measurements have drawn continuous efforts from a great deal of research. The bulk pH determination can tackle part of the demands from laboratories and industrial applications. However, more and more studies have started to pay more attention to microfluidic-based pH sensing by integrating with metal oxides and solid-state-based pH sensing applications. This review paper focuses on the recent development of pH sensing, the mechanisms of pH sensing, a few common pH sensors, and microfluidic-based pH determinations from the aspects of fabrication techniques to the various applications in biology, environmental study, and food safety. The future trends of pH sensing, as well as microfluidic-based pH sensing, were discussed as well at the end of this review. Full article
