Fundamentals of water electrolysis, and recent research progress and trends in the development of earth-abundant first-row transition-metal (Mn, Fe, Co, Ni, Cu)-based oxygen evolution reaction (OER) and hydrogen evolution (HER) electrocatalysts working in acidic, alkaline, or neutral conditions are reviewed. The HER catalysts include mainly metal chalcogenides, metal phosphides, metal nitrides, and metal carbides. As for the OER catalysts, the basic principles of the OER catalysts in alkaline, acidic, and neutral media are introduced, followed by the review and discussion of the Ni, Co, Fe, Mn, and perovskite-type OER catalysts developed so far. The different design principles of the OER catalysts in photoelectrocatalysis and photocatalysis systems are also presented. Finally, the future research directions of electrocatalysts for water splitting, and coupling of photovoltaic (PV) panel with a water electrolyzer, so called PV-E, are given as perspectives.

Hydrogen is considered af uture energy carrier that could improve energy storageo fi ntermittent solar/ wind power to solve energy and environmental problems. Based on such demand, development of electrocatalysts for hydrogen generation has been actively pursued. Although Pt is the most efficient catalyst for the hydrogen evolution reaction (HER), it hasl imits for widespread application, mainly its low abundance and high cost. Thus, developing an efficient catalyst from non-preciousm etals that are abun-dant and inexpensive remains an important challenge to replacemento fP t. Transition metals have been considered possible candidatest or eplace Pt-based catalysts. In this review,a mong the transition metals, we focus on recently developedm olybdenum-carbon( Mo-C)h ybrid materials as electrocatalysts for HER. In particular,t he synthesis strategy for Mo-C hybrid electrocatalysts and the role of various carbon nanocomposites in Mo-C hybrid systems are highlighted.[a] Dr.

Плазменная установка НИУ «МЭИ» предназначена для испытаний тугоплавких металлов и создания высокопористых материа-лов нового поколения, в том числе для испытаний материалов в обеспечение отечественной программы создания термоядерно-го реактора (ТИН и ДЕМО) и международного термоядерного реактора ИТЭР. Установка представляет собой плазменную ло-вушку с линейной мультикасповой конфигурацией магнитного поля со стационарным плазменным разрядом с параметрами плазмы, обеспечивающими возможность мощной плазменно-тепловой нагрузки, ожидаемой на материалы в стационарных ре-жимах термоядерного реактора. В экспериментах планируется разработать новую технологию создания высокоразвитой и вы-сокопористой структуры поверхности тугоплавких металлов, в том числе так называемый вольфрамовый «пух» с размером пор и нановолокон ~50 нм, обладающих новыми физико-химическими свойствами, что представляет значительный интерес для ядерных, химических, энергетических, биомедицинских технологий.Ключевые слова: установки с магнитным удержанием плазмы, плазменно-тепловые испытания материалов, материалы термо-ядерного реактора, вольфрам, молибден, наноструктурированная поверхность, ИТЭР, нанотехнологии. The plasma device at NRU «MPEI» has been constructed for testing of refractory metals and creating high-porosity materials of a new generation for Russian thermonuclear reactors (FNS and DEMO) and the international thermonuclear experimental reactor ITER. The device is a plasma trap with a linear multi-casp configuration of the magnetic field, a stationary plasma discharge and plasma parameters, which make possible the powerful plasma-thermal load expected for materials in stationary modes of a thermonuclear reactor. In the experiments, it is planned to develop a new technology for creating a highly roughened and highly porous structure of the refractory metals surface, including so-called tungsten «fuzz» with pore size and nanofibers of ~50 nanometers and new physical and chemical properties, which is of considerable interest for nuclear, energy, biomedical technologies technologies.
