Developing earth-abundant, active and stable electrocatalysts which operate in the same electrolyte for water splitting, including oxygen evolution reaction and hydrogen evolution reaction, is important for many renewable energy conversion processes. Here we demonstrate the improvement of catalytic activity when transition metal oxide (iron, cobalt, nickel oxides and their mixed oxides) nanopar...

PdCo subnanoalloys have been commonly used as a catalytic material in some important chemicalreactions, involving in fisher-tropsch reactions, and oxygen reduction reactions. In terms ofunderstanding the role of catalysis, these smallest bimetallic nanoparticles provide the simplestprototypes of Pd-Co bimetallic catalysts for different compositions. In this study, the effect o...

A simple and steerable method was adopted to synthesize well-distributed rutile TiO2 nanobundles on reduced graphene oxides through two-step hydrothermal methods. The rutile TiO2-RGO composites were used as the anode materials in lithium ion batteries for investigation, which had an original morphology and a reversible capacity of 300 mA h g(-1) at 0.6 C and 200 mA h g(-1) at 1.2 C after 500 cy...

Lithium-ion batteries (LIBs) are extensively used for power storage in most gadgets, electric vehicles (EV), and energy devices. Spent LIBs an excellent source of metals, which can be recycled reused new to reduce environmental impacts. Our current study reports bioleaching-mediated metal recovery from spent nickel-, manganese-, cobalt (NMC)-based at a high solid content, using autotrophic bact...

The consumption of lithium has increased dramatically in recent years. This can be primarily attributed to its use lithium-ion batteries for the operation hybrid and electric vehicles. Due specific properties, will also continue an indispensable key component rechargeable next decades. An average battery contains 5–7% lithium. These values indicate that used are a high-quality raw material reco...

Rare metals have become indispensable for the production of parts such as batteries, motors, and semiconductors, which are important achieving high functionality in products advanced industries decarbonized society xEV (electric vehicles) AI / IoT. As spread is promoted toward a society, demand in-vehicle lithium-ion batteries expected to increase significantly. Therefore, cobalt used positive ...

Nanowires and nanotubes have been the focus of considerable efforts in energy storage and solar energy conversion because of their unique properties. However, owing to the limitations of synthetic methods, most inorganic nanotubes, especially for multi-element oxides and binary-metal oxides, have been rarely fabricated. Here we design a gradient electrospinning and controlled pyrolysis method t...

Abstract Sustainable management of spent lithium‐ion batteries, LIBs, is an urgent and critical challenge due to the number such devices reaching end‐of‐life. Recycling can offer a path for recovery valuable raw materials as lithium cobalt, whose supply critical. Thus, it mandatory develop efficient ways selective Li Co from cathode degradation processes. In this study most updated organic acid...
