Water Electrolysis Using Thin Pt and RuOx Catalysts

An inexpensive, simple, and high-activity catalyst preparation method has been introduced in this work. Pt and RuOx catalysts were fabricated by soaking inexpensive graphite electrodes (pencil-lead graphite rod: PGR) in catalyst precursor solutions and using a simple flame-annealing method, which results in lower amount of Pt and RuOx catalyst layers. From X-ray photoelectron spectroscopy and

Recent Advances in Nanomaterial‐Modified Pencil

Pencil graphite electrodes (PGEs) have several advantages over other carbon‐based or commercial metal electrodes, Naoto Matsuo and Seigo Ito, Water Electrolysis using Flame-Annealed Pencil-Graphite Rods, ACS Sustainable, 10.1021, (2019). Crossref

CNTs can also be produced by diffusion flame synthesis, electrolysis, using solar energy, heat treatment of a polymer, or low-temperature solid pyrolysis. In flame synthesis, combustion of a portion of the hydrocarbon gas provides the elevated temperature required, with the remaining fuel conveniently serving as the required hydrocarbon reagent.

2021/2/23Abstract Water electrolysis is a sustainable approach for hydrogen production by using electricity from clean energy sources. However, both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) associated with water electrolysis are kinetically sluggish, leading to low efficiency in corresponding electrolysis devices. In addition, current electrocatalysts that can

Batteries should not burst into flames

graphite: Like diamond, graphite (the substance found in pencil lead) is a form of pure carbon. Unlike diamond, graphite is very soft. The main difference between these two forms of carbon is the number and type of chemical bonds between carbon atoms in each substance.

Polymer pencil lead graphite for in vivo radiation

2020/6/1Using a diamond knife, 250 pencil‑lead samples were prepared, each of length 0.5 0.1 cm. The mass of each sample was determined using an electronic balance (Metter Toledo), allowing TL intensity to be normalized to unit mass of the PPLG. The mean sample
