Summary: Defects on carbon nanotubes can be used to promote catalytic reactions, and a method involving reduction of CO2 in Li2CO3-based molten salts has been developed to synthesize defect-rich CNTs in an eco-friendly and controllable manner. The degree of defects in CNTs can be adjusted by changing the applied electrolysis current, with lower current favoring the synthesis of CNTs with more defect sites. These defect-rich CNTs, particularly the ones synthesized under 300 mA cm(-2) electrolysis, exhibit superior performance in the oxygen reduction reaction compared to those synthesized under higher current densities.

Summary: Oxygen reduction reaction via 3-electron pathway is a promising approach for generating reactive oxygen species in heterogeneous electro-Fenton (H-EF) process. Bimetal alloy nanoparticles encapsulated within carbon layers (FeCo/C) showed exceptional performance in sulfamethoxazole removal in the H-EF process, and the performance was enhanced under alkaline conditions. The involvement of a surface-independent outer sphere electron transfer component was identified as the mechanism for the alkalinity-enhanced activity.

Summary: Electrochemical modification is an effective method for preparing electrocatalytic materials. This study successfully fabricated a stable NiFeCuPt carbon matrix on nickel foam, with a very low Pt load. The obtained material served as a bifunctional catalyst for water splitting, achieving high current density at low cell voltages in both acidic and alkaline solutions. Additionally, a novel electrolyte was developed to stabilize the catalyst under acidic conditions.

Summary: A high-performance electrocatalyst Pt/3DNG for PEMFC applications has been developed by grafting an active triple-phase boundary on the 3DNG support material to precisely control the formation of the proton conducting ionomer interface at the active sites. Introducing the concept of in situ generation of the proton conducting-ionomer based active triple-phase boundary during electrode fabrication could potentially replace the conventional method of using Nafion ionomer for electrode preparation.

Summary: We demonstrated a facile pyrolysis method for synthesizing nitrogen-doped carbon-supported NiFe alloys (NiFe-NC) that exhibit excellent electrocatalytic activity for both CO2 reduction reaction (CO2RR) and oxygen reduction reaction (ORR). The NiFe-NC catalyst showed unprecedented CO2RR activity with a high CO faradaic efficiency and achieved a industrial current density and CO FE comparable to commercial catalysts for CO2RR. It also demonstrated impressive ORR performance comparable to commercial Pt/C catalysts. Moreover, the NiFe-NC was successfully used as a cathode material in Zn-air batteries and showed high power density. A self-driven CO2 flow electrolysis system powered by two series-connected NiFe-NC-based Zn-air batteries was designed and showed high efficiency in converting CO2 to CO. The results of this study provide insights for the development of efficient electrocatalysts for energy conversion and storage.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.

Summary: This study demonstrates a simple and environmentally-friendly method for the synthesis of zinc oxide nanozymes (ZnO NZs) using wasted hop extract (WHE). The WHE-ZnO NZs exhibit exceptional peroxidase-like activity and serve as effective catalysts for the oxidation of 3,3,5,5-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H2O2). In addition, a straightforward colorimetric technique for detecting both H2O2 and glucose was developed using the WHE-ZnO NZs as peroxidase-like catalysts.
