High surface carbon aerogels with hierarchical and tunable pore structure were prepared using ionic liquid as carbon precursor via a simple salt templating method. The as-prepared carbon aerogels were characterized by nitrogen sorption measurement and scanning electron microscopy. Through instant visual observation experiments, it was found that salt eutectics not only serve as solvents, porogens, and templates, but also play an important role of foaming agents in the preparation of carbon aerogels. When the pyrolyzing temperature rises from 800 to 1000°C, the higher temperature deepens the carbonization reaction further to form a nanoporous interconnected fractal structure and increase the contribution of super-micropores and small mesopores and improve the specific surface area and pore volume, while having few effects on the macropores. As the mass ratio of ionic liquid to salt eutectics drops from 55% to 15%, that is, the content of salt eutectics increases, the salt eutectics gradually aggregate from ion pairs, to clusters with minimal free energy, and finally to a continuous salt phase, leading to the formation of micropores, uniform mesopores, and macropores, respectively; these processes cause BET specific surface area initially to increase but subsequently to decrease. With the mass ratio of ionic liquids to salts at 35% and carbonization temperature at 900°C, the specific surface area of the resultant carbon aerogels reached 2309 m2 g–1. By controlling the carbonization temperature and mass ratio of the raw materials, the hierarchically porous architecture of carbon aerogels can be tuned; this advantage will promote their use in the fields of electrodes and adsorption.

Since the reform and opening up, China has maintained rapid economic growth for nearly 40 years, and is the country with the fastest economic growth in the world. However, the rapid economic growth has also paid a huge social price, which is directly related to the unreasonable economic structure and extensive growth mode. Traditional engines of economic growth began to fade. This paper through the analysis to the theory of ancient and modern Chinese and foreign economists study on economic growth: economic growth is an extremely complex process, many factors influence the economic growth, correctly grasp the role of these factors in economic growth, to grasp the law of economic growth, the correct understanding of modern economic growth is very important. Sustained economic growth in China, on the basis of dynamic analysis, combined with the current economic situation at home and abroad, as you can see, in the high-speed economic growth since reform, various factors have been attenuation or mutation, the major developed countries and regions for the adjustment of the external imbalance in pressure, the depth of the global economic growth and recovery of the factors of uncertainty, It is difficult to maintain and improve the driving force and source of China’s economic growth in the future. The current industrialization process has reached a historical and international high level and is nearing the end. The growth rate of industrial investment will slow down significantly in the future. The demographic dividend is gradually depleting, and the savings rate will gradually decrease in the future. The era of rapid economic growth brought by demographic dividend and high savings rate in a long period of time will change. Therefore, based on the perspective of supply side demand and the development of new industries, the paper analyzes the driving force of traditional economic growth in China in the past, and holds that the driving force of consumption upgrading and digital economy are the important driving force of economic growth, and strives to improve the consumption structure of residents, increase the consumption rate and vigorously develop digital economy. Shifting China’s economic growth from relying on external demand to relying on domestic demand will provide strong support for high-quality development.

Trade and investment and consumption are the three important engine of economic growth. In 2016, the contribution rate of consumption of China's economic growth reached 64.6%, more than 33 trillion yuan, the total retail sales of social consumer goods consumption has become the first constitution of the national economic growth. This marks, China has entered the consumption boom at the same time also means that China Daily chemical market has entered a rapid growth of the golden age, daily chemical industry usher in a new round of major development machine pedantic. Under the new situation, to a strong rise of local brands from its former glory, and how in foreign trade brand market competition, how to embody fully respect on consumption subject and how to obtain competitive advantage, comprehensive this faster growth in promoting consumption and promoting the development of the globalization of domestic brands, no doubt is of great strategic significance and realistic significance.
