Carbon-based brilliance: a novel approach to renewable energy in radiotherapy centers.

This article focuses on the development and characterization of activated carbon derived from green coconut shells as a sustainable material for energy generation and environmental applications. The activated carbon is chemically prepared using zinc chloride activation and characterized through techniques such as BET surface area analysis, FT-IR spectroscopy, and electrochemical testing. Notably, the study explores the use of this activated carbon in solar cells that harness scattered radiation from radiotherapy and radiology equipment, demonstrating its potential to convert dispersed radiation into electrical energy efficiently. The material exhibits high energy and power densities, suggesting its suitability for powering both large-scale applications and small electronic devices, thereby contributing to alternative energy solutions and CO2 adsorption efforts.
