DESCRIPTION:CO2/CO Utilization\, as the central part of C1 chemistry and C
 CUS\, becomes one of the most severe challenges for human society nowadays
 . During the utilization of carbon-based resources\, CO is the important i
 ntermediate molecules\, but CO2 is the end-product indicating the use-up o
 f carbon energy. In recent years\, tremendous efforts have been put on CO2
 /CO utilization trying to convert them back to chemical products or energy
 . \nHowever\, the amount of energy required to convert CO2 into an energy 
 product is certainly higher than that can be provided by the resulted ener
 gy product. Hence\, CO2 can be regarded as a carbon energy resource only i
 f renewable energy is available and incorporated into the energy products.
  Of course\, CO2 can be regarded as a carbon resource to provide compositi
 onal carbon element for new chemical molecules. As a result\, CO2 can be r
 egarded as an energy carrier for the transformation of renewable energy.  
 Different from CO2\, CO is not so difficult to be activated but selective 
 control sounds not so easy for target products\, which is typical of synga
 s conversion into hydrocarbons or oxygenates. In particular\, CO2 is usual
 ly the by-product of syngas conversion. \nIn chemistry\, CO2 utilization p
 lays a role to complete the redox cycle\, which is intrinsically redox rea
 ctions in nature. Charge transfer is the key step for the occurrence of th
 e reactions. Moreover\, charge transfer capability is critical for develop
 ing the related catalytic materials. As for CO utilization\, the selective
  control becomes the key issue for syngas conversion into fuels or chemica
 ls.  \nNano/sub-nano catalysis plays a key role in the development of new 
 technologies for CO2 and CO utilization. Among them\, four key factors can
  be summarized for nano/sub-nano catalysis.\nλ	Single - single atom and s
 ingle site catalysis\; \nλ	Size - nano particle\, nano crystal\, and nano
  composite catalytic materials\;\nλ	Scale - descriptor or quantitative fa
 ctors\, such as distance\, distribution\, coverage\, etc. In nano catalysi
 s\, also including mesoscale understandings for nano catalysis\;\nλ	Surro
 unding - chemical environment and geometric environment for active sites.\
 nBooming recent publications concerning CO2 and CO utilization demonstrate
  the importance of C-O bond avtivation by nano/sub-nano catalysis with res
 pect to the factors above mentioned.\n
