Abstract:As a pillar industry in supporting Chinese economy, Chinese manufacturing industry consumes a large amount of energy and causes serious environmental pollutants. Better understanding the greening level of manufacturing industry is important to promote its green growth. Hence first this study, measures the green growth efficiency for Chinese manufacturing industries by applying the EBM measuring model; second, to better understand the differences and similarity in green growth among those industries, this study categorizes those industries into different types by using cluster analysis. The result shows that within the past nine years, green growth efficiency value for Chinese manufacturing industries rises steadily year by year, and Chinese manufacturing industries have huge promotion potentials in resource saving and environment pollutant reduction. And the characteristics of each different type are analyzed. Finally, policies and suggestions are put forward to promote the green growth of manufacturing industries in China. This study objectively evaluates the green growth level of Chinese manufacturing industry, which is helpful to understand the status quo and also explore green growth path for Chinese manufacturing industries.

In this paper, crystalline V 2 O 3 and amorphous V 2 O 3 /C products are synthesized via one-pot solution combustion synthesis (SCS) method (completed within 2 minutes).The characteristics of combustion products could be tuned by changing the amounts of glucose. The as-synthesized crystalline V 2 O 3 nanopowder consists of nanoparticles with average size of ~100 nm. Amorphous V 2 O 3 /C composite exhibits large porous microsheet structure in which oxygen vacancy-enabled amorphous V 2 O 3 particles are embedded into N-doped carbon microsheets. The existence of oxygen vacancies can promote energetics for the transport of electrons and ions and maintain the integrity of sample surface morphology. Moreover, N-doping can enhance electrical conductivity and promote the diffusion of electrons and lithium ions. Amorphous V 2 O 3 /C composite possesses high reversible capacity and superior cycling stability (833 mAh g −1 at 1 A g −1 after 250 cycles, 867 mAh g −1 at 0.1 A g −1 after 100 cycles), indicating its potential as excellent anode material for lithium-ion battery. The proposed one-step, time-and energy-efficient SCS method has the potential to prepare other oxygen vacancy-enabled transition metal oxides for energy storage.
