      abstract     = {The recycling of precious metals, for example, platinum, is
                      an essential aspect of sustainability for the modern
                      industry and energy sectors. However, due to its resistance
                      to corrosion, platinum-leaching techniques rely on high
                      reagent consumption and hazardous processes, for example,
                      boiling aqua regia; a mixture of concentrated nitric and
                      hydrochloric acid. Here we demonstrate that complete
                      dissolution of metallic platinum can be achieved by induced
                      surface potential alteration, an ‘electrode-less’
                      process utilizing alternatively oxidative and reductive
                      gases. This concept for platinum recycling exploits the
                      so-called transient dissolution mechanism, triggered by a
                      repetitive change in platinum surface oxidation state,
                      without using any external electric current or electrodes.
                      The effective performance in non-toxic low-concentrated acid
                      and at room temperature is a strong benefit of this
                      approach, potentially rendering recycling of industrial
                      catalysts, including but not limited to platinum-based
                      systems, more sustainable.},
