“…The revolution in information communication technology has led to an abundance of E‐wastes in many countries, but innovative ways to deal with this waste are appearing. The re‐use of waste manganese batteries is attracting research as an abundant source of waste metal oxides: some 60 billion manganese‐based batteries are produced annually 19 . For example, Lu Zhan et al 20 recently produced nano‐zinc oxide for potential sensing and catalysis applications, from discarded zinc‐manganese batteries, as shown in Figure 1A.…”

Summary There are abundant sources of metal‐oxide‐based wastes from industries such as electronics and metal production, which generally have a detrimental effect on the environment when not recycled. In this concise review, we aim to provide a brief overview of the state‐of‐the‐art research on how these metal‐oxide wastes are being used by the scientific community in the applications of energy storage, catalysis, and sensing. We focus on three important waste streams: E‐waste, waste from the production of metals, such as red mud and slag, and waste from metal recovery, for example, rusted wires and discarded capacitors. We review some promising routes for obtaining high‐quality metal‐oxide nanoparticles and nanowires and critically review potential pitfalls that hinder the wide‐scale application of these waste‐streams.

En las pilas alcalinas de Zn/MnO2 , el dióxido de manganeso electrolítico (DME) se utiliza como cátodo y constituye una parte muy importante de los residuos domésticos que aportan metales pesados a los residuos sólidos urbanos. Este estudio describe la recuperación de DME por electro-oxidación en tela de carbón en licores ácidos lixiviados de baterías alcalinas usadas. Los rendimientos máximos de extracción para Mn y Zn fueron 43,68% (0,744 molL-1 ) y 56,11% (0,7321 molL-1 ) respectivamente. Los voltamogramas de un electrodo de carbón vítreo para la deposición de DME a partir de licores lixiviados se obtuvieron entre 0,0 y 1,4 V frente a ECS, y presentan un pico anódico a 1,2 V frente a ECS. Además, aparece un pico catódico a 0,97 V frente a ECS. La difracción de rayos X revela la presencia de nsutita (γ-MnO2) y manganita (γ-MnOOH) para todos los depósitos, y la morfología de los depósitos fue observada por microscopia electrónica de barrido (SEM).
