On January 10th, the 2022 "Science and Technology Innovation China" series of rankings released by the China Association for Science and Technology underwent preliminary and final evaluations, selecting 150 leading technologies, 100 emerging enterprises, 10 innovative organizations, 50 entrepreneurship and employment pioneers, 20 technology managers, 50 international innovation cooperation, and 30 open source innovation, totaling 410 projects to be included in the list. Zhongzi Environmental Protection Technology Co., Ltd.'s "National VI Natural Gas Vehicle Exhaust Purification Catalyst" technology has been selected for the "Science and Technology Innovation China" Leading Technology List - Advanced Materials Field List.

Zhongzi Environmental Protection Technology Co., Ltd. (hereinafter referred to as the "Company", stock code: 688737), founded in 2005, was listed on the Science and Technology Innovation Board of the Shanghai Stock Exchange in 2021. The company is committed to the research and promotion of catalysts (devices) for post-treatment of emissions from natural gas, diesel, gasoline and other fuel engines, as well as new materials and energy technologies such as hydrogen fuel cell electrocatalysts, energy storage and power batteries. It is a key high-tech enterprise under the National Torch Plan that integrates research and development, production, sales and services.

Due to the relatively late development of China's automobile industry, its automobile exhaust catalysts have always been monopolized by several international giants. Since June 2016, the company has officially launched the development of natural gas National VI catalyst technology and products. By continuously increasing research and development investment, it has deeply cultivated the field of natural gas vehicles. In 2019, it was the first in the industry to mass produce the first generation of cost-effective platinum, palladium, and rhodium three-way catalysts that meet the emission requirements of National VI natural vehicles, breaking through the bottleneck problem in this key field and breaking the monopoly of international industry giants. In May 2022, the national key research and development plan "Development and Industrialization of Key Technologies for Pollution Emission Control of Alternative Fuel Vehicles" led by the company was evaluated for its achievements. The attending expert group unanimously agreed that the project has strong innovation, achieved independent and controllable core technology of natural gas vehicle catalysts, and overall technology is at the international leading level, leading the industry's technological development.

Since its establishment in 2005, the company has been deeply involved in the field of environmental protection catalysts, dedicated to the research, development, production, and sales of catalysts (devices) for exhaust after treatment of natural gas, diesel, gasoline and other fuel engines, industrial catalysts, as well as new energy products such as energy storage and power batteries, hydrogen fuel cell electrocatalysts, etc. In the future, the company will continue to uphold the mission of "controlling air pollution and realizing the dream of blue skies and white clouds", deeply cultivate the fields of new materials and new energy, reduce pollution and carbon emissions, and help achieve the national "dual carbon" goal as soon as possible.
