成果简介	NOVELTY - The process for synthesizing flower-like cesium tantalate involves: mixing 0.32-1.2 kg tantalum(V) oxide with 0.6-1.8 kg betel-nut seed powder; transferring the mixture into a beaker containing a cesium carbonate solution with a molarity of 1.2-1.8 M and stirring until a homogeneous solution is obtained; gradually evaporating the water from the homogeneous solution using a water bath to yield a sponge-like material; calcining the sponge-like material in a pre-heated muffle furnace at 680-930° C for 7-9 hours; and cooling the calcined material to room temperature to produce a light brown crystalline powder catalyst. USE - Process for synthesizing flower-like cesium tantalate useful as catalyst for photocatalytic hydrogen generation experiments (claimed), and in wastewater treatments ADVANTAGE - The process provides an efficient method for synthesizing nanostructured catalysts with high photocatalytic performance for environmental remediation. The dye, preferably methylene blue dye degradation, monitored through periodic sampling, is achieved within 20-45 minutes with an efficiency of 95-99%. The method demonstrates exceptional efficacy, achieving 99.6% dye degradation within minutes under UV-visible light. The method does not relay on costly noble metal catalysts and employs alternative, cost-effective, and environmentally friendly materials, enhancing its sustainability. The rapid dye degradation minimizes processing time and resource usage, offering a competitive edge in industrial applications that prioritize efficiency. The innovative pilot-scale photocatalytic process excels in its effectiveness, rapidity, affordability, and suitability for real-world applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a photocatalytic reaction system for hydrogen generation using the catalyst, which comprises a closed gas circulation system with a capacity of 1.4-1.8 liters, a quartz cell to house a mixture of reactant solution and catalyst, where the catalyst constitutes 0.1-0.3% the reactant solution, and a reactant solution comprising either 0.8-1.2 liters pure water for water splitting into hydrogen and oxygen, or aqueous solutions of 2.2-3.4% methanol and 0.18-3.4% EDTA for hydrogen generation.
