To find an effective alternative to scarce, high-cost noble platinum (Pt) electrocatalyst for hydrogen evolution reaction (HER), researchers are pursuing inexpensive and highly efficient materials as an electrocatalyst for large scale practical application. Layered transition metal dichalcogenides (TMDCs) are promising candidates for durable HER catalysts due to their cost-effective, highly active edges and Earth-abundant elements to replace Pt electrocatalysts. Herein, we design an active, stable earth-abundant TMDCs based catalyst, WS(1−x)Sex nanoparticles-decorated onto a 3D porous graphene/Ni foam. The WS(1−x)Sex/graphene/NF catalyst exhibits fast hydrogen evolution kinetics with a moderate overpotential of ~−93 mV to drive a current density of 10 mA cm−2, a small Tafel slope of ~51 mV dec−1, and a long cycling lifespan more than 20 h in 0.5 M sulfuric acid, which is much better than WS2/NF and WS2/graphene/NF catalysts. Our outcomes enabled a way to utilize the TMDCs decorated graphene and precious-metal-free electrocatalyst as mechanically robust and electrically conductive catalyst materials.

AbstractThere is a general consensus to develop renewable energy storage and conversion technologies to replace fossil fuel energy for sustainable development. Currently, the development of high performance energy storage and conversion devices is an important step on the road to alternative energy technologies. With a special focus on the upgradation of waste to valuable energy, this paper presents an effective synthetic method that utilizes waste newspapers as the precursor to prepare the activated carbon electrodes by the pyrolysis and chemical activation processes. The amorphous nature and surface morphology of the carbon samples were confirmed by XRD and SEM analysis, respectively. Activated waste newspaper carbon (AWNP) showed good electrochemical properties at 800 °C and its specific capacitance at a scan rate of 2 mV/s was found to be 380 F/g. It is important to mention that the source of the raw material is cost effective and suitable for green technology.

And Performance

Energy storage and conversion are major problems of our modern society. In the last decades, in order to minimize these problems, a growing research activity was dedicated to the development of new systems involved in this energy field. The fabrication of supercapacitors based on new materials, such as electrochemical double layer capacitor, can offer attractive potentialities. Indeed, these supercapacitors are able to provide a power density ten times higher than that supplied by batteries, and allow a larger number of charge and discharge cycles. The performance of supercapacitors highly depends on the properties of electrode materials. Ternary composites combining both capacitive and faradaic reactions can address the improvement necessary for relatively cost effective and performance of supercapacitors. Particularly, ternary nanocomposites systems of carbon nanotubes (CNTs), conducting polymer (CPs) films and metal oxide/hydroxide; CNT:CP:Metal oxide; has been proposed as potential electrodes for electrochemical supercapacitors, as alternatives to overcome the drawbacks associated with single component electrodes for the construction of high performance supercapacitors.
