Using a simple hydrothermal procedure, cobalt oxide (Co(3)O(4)) nanowires were in situ synthesized on three-dimensional (3D) graphene foam grown by chemical vapor deposition. The structure and morphology of the resulting 3D graphene/Co(3)O(4) composites characterized scanning electron microscopy, transmission X-ray diffraction, Raman spectroscopy. composite was used as monolithic free-standing electrode for supercapacitor application enzymeless electrochemical detection glucose. We...
Owing to their small size, biocompatibility, unique and tunable photoluminescence, physicochemical properties, graphene quantum dots (GQDs) are an emerging class of zero‐dimensional materials promising a wide spectrum novel applications in bio‐imaging, optical, electrochemical sensors, energy devices, so forth. Their widespread use, however, is largely limited by the current lack high yield synthesis methods high‐quality GQDs. In this contribution, facile method electrochemically exfoliate...
Graphene, a single-atom-thick monolayer of sp(2) carbon atoms perfectly arranged in honeycomb lattice, is an emerging sensing material because its extraordinary properties, such as exceptionally high specific surface area, electrical conductivity, and electrochemical potential window. In this study, we demonstrate that three-dimensional (3D), macroporous, highly conductive, monolithic graphene foam synthesized by chemical vapor deposition represents novel architecture for electrodes. Being...
Abstract Two‐dimensional materials have attracted increasing research interest owing to their unique electronic, physical, optical, and mechanical properties. We thus developed a general strategy for the fabrication of ultralong hybrid microfibers from mixture reduced graphene oxide transition‐metal dichalcogenides (TMDs), including MoS 2 , TiS TaS NbSe . Furthermore, we prepared fiber‐based solid‐state supercapacitors as proof‐of‐concept application. The performance thus‐prepared was...
Graphene quantum dots (GQDs) are emerging fluorescence reporters attractive for optical sensing, owing to their high photostability, highly tunable photoluminescence, molecular size, atomically thin structure, biocompatibility, and ease of functionalization. Herein, we present a fluorometric sensing platform based on tyramine-functionalized GQDs, which is able detect spectrum metabolites with sensitivity specificity. Furthermore, multiparametric blood analysis (glucose, cholesterol,...
A novel graphene–cobalt oxide hybrid needle-like electrode was fabricated for non-enzymatic glucose detection. Taking advantage of its small size, the needle can probe in a micro-droplet with high sensitivity.
Hydrogen and valuable formate are simultaneously produced at low cell voltage from seawater splitting with the assistance of methanol selective oxidation to suppress undesired oxygen/chlorine evolution over Pt-Co<sub>3</sub>O<sub>4</sub> bifunctional electrocatalysts.
Electrocatalytic N2 oxidation (NOR) into nitrate is a potential alternative to the emerging electrochemical reduction (NRR) ammonia achieve higher efficiency and selectivity of artificial fixation, as O2 from competing oxygen evolution reaction (OER) potentially favors oxygenation NOR, which different parasitic hydrogen (HER) for NRR. Here, we develop an atomically dispersed Fe-based catalyst on N-doped carbon nanosheets (AD-Fe NS) exhibits exceptional catalytic NOR capability with...
Efficient and robust single-atom catalysts (SACs) based on cheap earth-abundant elements are highly desirable for electrochemical reduction of nitrogen to ammonia (NRR) under ambient conditions. Herein, the first time, a Mn-N-C SAC consisting isolated manganese atomic sites ultrathin carbon nanosheets is developed via template-free folic acid self-assembly strategy. The spontaneous molecular partial dissociation enables facile fabrication process without being plagued by metal atom...
Microfiber devices are able to extend the micro/nano functionalities of materials or macroscopic scale with excellent flexibility and weavability, promising a variety unique applications and, sometimes, also improved performance as compared bulk counterparts. The fiber electrodes in these often made carbon (e.g. nanotubes graphene) because their exceptional electrical, mechanical, structural properties. Covering latest developments aiming stimulate more exciting applications, we...
Hierarchically porous carbons are attracting tremendous attention in sustainable energy systems, such as lithium ion battery (LIB) and fuel cell, due to their excellent transport properties that arise from the high surface area rich porosity. The state‐of‐the‐art approaches for synthesizing hierarchically normally require chemical‐ and/or template‐assisted activation techniques, which is complicate, time consuming, not feasible large scale production. Here, a molecular‐level design principle...
Biofuel cells (BFCs), which use enzymes as catalysts to harvest energy from green and sustainable fuels abundantly producible biological systems, are promising next-generation devices. However, the poor stability high specificity only one fuel type of these bio-catalysts largely limits practical current BFCs. In this contribution, we demonstrate a unique cell which, equipped with two identical enzyme-free electrodes based on Co3O4 coated 3D graphene, is able efficiently electricity various...
