AI Technical Summary

Technical Problem

In the existing photocatalytic technology, long afterglow catalytic materials are prone to saturation, resulting in low utilization of solar energy, and the delayed catalytic capacity will continue to decline after the excitation light stops.

Method used

A stacked CO2 catalytic reduction device based on long afterglow catalytic material is adopted, and a stack structure is formed by staggered installation of multiple roller shafts. The driving motor drives the roller shaft to rotate at a preset speed, driving the cyclic movement of the long afterglow catalytic film material to ensure that different parts of the film material are sequentially exposed to sunlight.

Benefits of technology

The stack structure improves solar energy utilization, extends the activity time of the catalytic material, significantly increases the rate of CO2 reduction reaction, and reduces the complexity and cost of the device.
