In this study, different carbon nanomaterials (carbon nanotubes, solid carbon spheres and graphene nanosheets) for immobilizing bacterial small laccase (SLAC) to enable direct bioelectrocatalysis of oxygen reduction were comparatively investigated. H

The performance of the Electro-Fenton (EF) process for contaminant degradation depends on the rate of H2O2 production at the cathode via 2-electron dissolved O2 reduction. However, the low solubility of O2 (≈1 × 10−3 mol dm−3) limits H2O2 prod

Herein, for the first time, ball-milling of carbon materials (e.g. graphite, graphene oxide or graphene) in the presence of dicyandiamide (DCDA) followed by heat treatment at 800 °C was employed to synthesise N-doped carbons for the oxygen reduction

Fluorine-intercalated graphite, CxF with x = 2.8, was tested for the cathode active material of an all-solid-fluoride-ion shuttle battery. The addition of copper fluoride facilitated the discharge reaction of CxF. It was discharged up to 0.4 V vs. Pb

In this work, a novel amperometric biosensor based on carbon nanoplatelets derived from ground cherry (Physalis peruviana) husks (GCHs-CNPTs) is reported for the sensitive and selective detection of ascorbic acid (AA). The structure of the nanoplatel

Ag-Co3O4@N-doped carbon/carbon nanotubes composites are synthesized by dispersing Ag nanoparticles throughout the N-doped carbon derived from ZIF-67/CNT. In oxygen reduction reaction (ORR), the synthesized composites possess a one-step 4 electron pat

Potassium-ion batteries (KIBs) are a promising sustainable energy storage technology due to the high abundance and low cost of potassium. Carbon anode materials for KIBs have seen great successes, but the development of cathode materials is yet to ca

Poor rechargeability is one of major drawbacks of lithium-air batteries. Our study reveals that the accumulation and subsequent removal of reaction products during cycles can lead to a serious disruption and volume expansion of the cathode structure

In this communication, we present some new findings on surface oxidized carbon nanotubes (CNTs) when used as cathode of Li–O2 batteries. It is found that the content of oxygen-containing functional groups has a significant influence on the electroc
