Microwave Popped Co(II)-Graphene Oxide Hybrid: Bifunctional Catalyst for Hydrogen Evolution Reaction and Hydrogen Storage

Abstract

In an effort to develop a multifunctional catalyst for hydrogen generation and adsorption applications, a facile and cost-effective microwave popping method was used to synthesize popped graphene oxide (PGO) and Co-PGO hybrid. Both samples have been explored and compared as hydrogen storage materials and as electrocatalysts for hydrogen evolution reaction (HER) for the first time. The loading of Co(II) species on the surface of the PGO enhanced the hydrogen storage capability of PGO from 0.04wt% to 0.08wt% as measured at 293K and 800 mmHg. Co-PGO is also acting as a better electrocatalyst for HER compared to the PGO counterpart.

Two‐Step Deposition Approach for Lead Free (NH4)3Sb2I9 Perovskite Solar Cells with Enhanced Open Circuit Voltage and Performance

“…Production of green energy units including hydrogen, [1–6] batteries, [7–11] supercapacitors [12–14] and solar cells [15] by low‐cost methods is of great importance. Solar energy harvesting using perovskite or perovskite‐like materials is trending due to cost‐effective and simple fabrication techniques [15–29] .…”

Graphene Oxide-based Nanomaterials for Uranium Adsorptive Uptake

“…[14,47] Due to these oxygen-containing functional groups, GO possesses features such as high dispersion, hydrophilicity, and compatibility, making it a suitable support material to combine with other chemical functional groups or composites as demonstrated in our previous studies among many others. [68,69] Meanwhile, the functional groups of GO can provide active adsorption sites for environmental pollutants, such as uranium and other radioactive species in wastewater. For the past few years, a large number of studies on GO-based nanomaterials as adsorbents of uranium have been carried out.…”

The Properties and Preparation Methods of Different Boron Nitride Nanostructures and Applications of Related Nanocomposites

“…The use of hydrogen energy provides an effective way to solve the problem of air pollution, [174] but the safe use and storage of hydrogen resources has become the first problem that researchers need to solve. [175][176][177] BN nanomaterials with good chemical and thermal stability, light mass density, especially BNNSs with 2D structure and BNNTs similar to carbon nanotube structure, have special surface hydrogenation and selective adsorption properties, which make them have great application potential in the field of hydrogen storage. [178,179] For example, Lei et al [180] synthesized BNNSs containing 2-6 layers without the use of any catalyst and template, and the oxygen-doped BNNSs exhibited a hydrogen storage capacity of up to 5.7 wt%.…”
