Title: Alfred C. Tseung: Innovator in Metal Protection and Electrocatalysis
Introduction
Alfred C. Tseung is a notable inventor based in London, GB. He has made significant contributions to the fields of materials science and electrochemistry, holding a total of 7 patents. His work primarily focuses on preventing hydrogen embrittlement in metals and developing efficient electrocatalysts.
Latest Patents
One of his latest patents addresses the prevention of hydrogen embrittlement of metals in corrosive environments. This invention is crucial for metal substrates in gas and oil pipelines, which are susceptible to embrittlement due to hydrogen absorption during corrosion processes. Tseung's method involves providing an active substance, such as a sulphide or mixed sulphide of a metal from Groups Vb, VIb, or VIIb of the Periodic Table, in contact with the metal substrate. This active substance is typically applied as a coating, often overcoated with a thermosetting resin for added protection.
Another significant patent by Tseung relates to lithiated cobalto-cobaltic oxides, particularly stoichiometric Co₃O₄. These materials have been identified as highly efficient electrocatalysts, especially when containing lithium at levels exceeding 2 atom percent. They are particularly effective for oxygen evolution and reduction electrodes and demonstrate long-term stability, lasting up to 6,000 hours. Additionally, these electrocatalysts are applicable in chemical processes involving the decomposition of hydrogen peroxide or peroxyl ions.
