Silicon oxycarbides can be considered as being carbon‐containing silicates consisting of glass networks in which oxygen and carbon share bonds with silicon. The carbon‐for‐oxygen substitution in silicate glass networks has been shown to induce significant changes in the network connectivity and consequently strong improvements in the properties of the silicate glass network. For instance, SiOC glasses exhibit Young's moduli, hardness values, glass transition, and crystallization temperatures which are superior to those of vitreous silica. Moreover, the silicon oxycarbide glass network exhibits unique structural features such as reduced mass fractal dimension and nano‐heterogeneity, which significantly affect and/or dictate its properties and behavior. In the present Review, a consideration of the current state of the art concerning the synthesis, processing, and various structural and functional properties of silicon‐oxycarbide‐based glasses and glass‐ceramics is done. Thus, the synthesis of silicon oxycarbides starting from macromolecular precursors such as polysiloxanes or alkoxysilanes‐based sol‐gel systems as well as current advances related to their processing will be critically reviewed. In addition, various structural and functional properties of silicon oxycarbides are presented. Specific emphasis will be put on the intimate correlation between the molecular architecture of the precursors and the structural features and properties of the resulting silicon oxycarbides.

“…Since the benefit of low-carbon projects such as energy saving and environmental protection cannot be translated into economic benefits, it conflict between the goal of social benefits in low-carbon economy and the goal of pursuing profit in financial institutions. Due to the lack of current economic benefits, financial institutions are unable to cope with the social cost brought about by environmental changes [2]. The financial regulatory regime strictly requires of safety, profitability and liquidity.…”

Heavy industry would consume a lot of energy and make serious pollution, so it is important to develop a low-carbon economy for the need of not only changing the mode of economic development, but also building an ecological city. However, in the process of developing a low-carbon economy, there are many problems such as slowly development of carbon alternative industry, backward technology level, short of financing method for low-carbon economy. Therefore, it is important to accelerate the transformation of resource-based cities, promote the recycling of resources, develop alternative and renewable energy resources, improve the financing environment for low-carbon economy, and improve the development of carbon trading.

Melt spun silicone resin fiber with a diameter of 14 µm was exposed to TiCl 4 vapor with flowing nitrogen at room temperature or 40°C. During the exposure, TiCl 4 was incorporated in the resin network with formation of cross-links. After standing in ambience for 24 h and pyrolysis in an air flow, SiO 2 TiO 2 fibers were obtained in a yield of 7580%. Ti/Si content can be controlled by adjusting the curing time and temperature. TiO 2 existed as nano particles or aggregated large particles, which were strongly attached on the fiber body. Analysis of 2-propanol degradation by the fiber under UV light suggested the existence of photocatalytic activity.
