4. Low-Cost Alternative Technology for Non-Precious Metal VOCs Catalysts
【Achievement Summary】
In response to the high costs, weak anti-poisoning capabilities, and insufficient high-temperature stability of precious metal (Pd, Pt, Ru) catalysts in the field of industrial VOCs treatment, our team has successfully developed a series of non-precious metal catalyst systems. This technology innovatively optimizes component allocation and structural regulation, significantly enhancing environmental tolerance while maintaining VOCs purification efficiency comparable to that of precious metal catalysts, thus providing a cost-effective solution for industrial waste gas treatment.
【Technical Indicators】
Core Components: Non-precious metals such as La, Fe, Co, Ni, Cu, Mn as the main active components;
Removal Efficiency: Within the operating temperature range (200-300℃), the removal efficiency for typical VOCs such as benzene, toluene, and xylene is ≥98% (comparable to precious metal catalysts);
Catalyst Stability: Excellent resistance to sulfur, sintering, and carbon deposition, with a stable operating time exceeding 1000 hours;
Equipment Compatibility: Compatible with existing fixed bed/fluidized bed catalytic combustion devices without the need to modify reactor structures.
【Application Prospects】
Non-precious metal catalysts, as potential substitutes for precious metal catalysts, have been successfully applied in VOCs treatment in industries such as steel, coking, refining, and pharmaceuticals. While ensuring unchanged treatment efficiency, their lifecycle costs can be reduced by 50%-60% compared to precious metal catalysts. This not only provides industrial enterprises with a more cost-effective solution but also strongly supports the widespread application of VOCs treatment technology and industrial upgrading.
5.CO₂–Mg Gas-Liquid Reaction for the Preparation of High-Quality Graphene and Modifier
【Achievement Summary】
With the implementation of the national “dual carbon” strategy, how to efficiently address the emission and utilization of CO₂ gas has become a hot topic in current scientific development. Although traditional chemical catalytic methods can effectively convert CO₂ gas into organic substances, they face issues such as low efficiency, poor results, and complicated processes. In response, our team proposed a method utilizing highly chemically active alkaline metal Mg to react with CO₂ gas in a molten state for in-situ gas-liquid reaction, synthesizing high-quality graphene and efficient magnesium alloy modifiers in one step. This method has significant advantages of simplicity, high efficiency, and low cost.
【Technical Indicators】
The graphene produced from the CO₂-Mg gas-liquid in-situ reaction has significant advantages such as low defect content, high crystallinity, thin layers, and large flake size, with a thickness of approximately 3nm to 10nm and flake sizes ranging from 0.5μm to 5μm; the refinement efficiency of the produced magnesium alloy modifier can reach over 70%.
【Application Prospects】
High-quality graphene is widely used in fields such as lithium-ion batteries, semiconductor materials, electronic devices, biomedical applications, and composite materials. For example, graphene films can be used to create transparent conductive layers, enabling flexible smartphone screens and display modules for smart wearable devices, with companies like Samsung already launching related products.
