Catalyzing Biomass Concrete as New Renewable Energy Source for Green Building

This paper focuses on Catalyzed Biomass Concrete (CBC) as a sustainable solution for electricity generation with investigate the viability of using palm oil fuel ash (POFA) as a partial replacement for cement and explore the effects of four types of Polyoxometalates (POMs) as catalysts. By utilizing solar-induced biomass and POMs as catalysts, CBC is employed in compressive strength analysis, voltage tests, and engineering tests. Engineering tests and analyses such as thermogravimetry analysis (TGA), and X-ray fluorescence (XRF) are employed to investigate the engineering properties of different CBC samples and support the research findings. Results show that CBC with Phosphomolybdic Acid + Ferric Chloride excels in voltage generation and compressive strength at day 56, while CBC with Phosphotungstic maintains consistent strength, improving notably from day 7 to 56, indicating reliability as a catalyst. In voltage tests, CBC with Phosphotungstic consistently exhibits stability and voltage generation within the specified temperature range. CBC with Ferric Chloride Solution and Silicotungstic Acid's varying mV values suggest effectiveness dependent on POM content, potentially limiting precise electrical characteristics. These findings highlight the potential of CBC as an environmentally friendly alternative for electricity production in the construction industry.
