2D MXenes as Co-catalysts in Photocatalysis: Synthetic Methods

“…Energy shortage and environmental pollution have become the two major issues faced by humanity due to limited fossil fuel resources and increasing consumption. Developing sustainable and clean energy is the key to addressing these two problems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In being clean and inexhaustible, solar energy shows great potential to be one of the most promising future energy sources.…”

High-performance coaxial wire-shaped supercapacitors using ionogel electrolyte toward sustainable energy system

“…Furthermore, ionogel utilized as solid-state electrolyte exhibits high thermal/electrochemical stability, which effectively ensures the great reliability and high operating voltage of coaxial WSSCs. Compared with other energy conversion and storage units [59,60,61,62,63,64,65,66], coaxial WSSCs not only show superior flexibility and wearability but also exhibit low resistance, high volumetric energy density (3.2 mW h/cm 3 ), and strong durability (82% after 10,000 cycles). More importantly, the coaxial WSSCs device with high voltage of 3 V can be effectively recharged by harvesting sustainable wind source and repeatedly supply power to the lamp without a decline of electrochemical performance.…”

Multifunctional High‐Performance Electrocatalytic Properties of Nb2O5 Incorporated Carbon Nanofibers as Pt Support Catalyst

“…Nb 2 O 5 is an n‐type semiconductor (3.4 eV bandgap) with the exceptional microtextural property, high refractive index, excellent chemical stability, and good corrosion resistance. Hence, Nb 2 O 5 has found potential applications in various fields such as catalysis, lithium‐ion batteries, electrochromic devices, and photovoltaic cells . Mainly, Orilall et al have prepared a Pt–Pb loaded niobium oxide‐carbon composite by three‐step anionic polymerization technique and demonstrated it as an effective catalyst for formic acid electro‐oxidation .…”
