2.2 Undertake a literature survey (via the internet, research journals, books etc) and (i) (ii) (iii) Attach a picture of a potentiodynamic polarisation curve of a metal (or alloy) that undergoes uniform attack in a given test solution (5 marks) What were the settings/parameters used for running the potentiodynamic polarisation test? (5 marks) Provide explanations on why the metal (or alloy) undergoes uniform attack in the test solution? (5 marks) Note: Do not use pictures from lecture/workshop/applied class notes. There must be proper referencing of any content (pictures/ideas/text) taken from external sources. 2.3 Several researchers are seeking to develop electrolysers (or electrochemical reactors), to electrochemically reduce dissolved carbon dioxide in water to fuels (such as formic acid, methane....). How are such reactors expected to work?
