(5th period) are metalloids and their oxides are amphoteric in nature. However, bismuth (6th period) is a metal. Thus, we can see that the electronegative character (non-metallic character) of elements gradually decreases and ultimately the last element becomes metal. In case of group 17 of ...
Forming a metal oxide by treating an acidic solution containing a metal to yield a precursor in the form of a semi-liquid, semi-solid or solid, and treating the precursor to yield a product including the metal oxide. An organic or inorganic component may be combined with the precursor to ...
The operating stability is the key issue when considering the implementation for the practical application since most metal oxides are prone to dramatically activity loss under acidic OER condition. Therefore more reliable data collection is performed, based on the standard measurements proposed by Kibsgaa...

29 used graphene oxides (GO) to remove radionuclides from acidic wastewaters (pH < 2); this study described heavy actinide sorption kinetics on GO surfaces, suggesting that GO is more effective for the removal of transuranic elements from wastewater than many conventional sorbents. However, GO...
