The ongoing energy transition based on the substitution of fossil feedstocksa se nergy sourcesw ith renewablee nergy (RE) sourcesdemands reconsideration of current industrial chemical production,w hich is anticipated to be at the end of this cycle. The main element determining greenhouse gas (GHG) emissions during chemical production is the use of fossil fuels to drive chemical transformations, rather than their use as sources of carbon.F urthermore, RE will become progressively cheaper as as ource of energy with respectt ot hat derived fromf ossil fuels and new chemical raw materials such as methanol, derived from the conversion of waste CO 2 ,w illb ecome available on al arge scale, being used as energy vectors to transport RE on ag lobals cale. There are thus converging sustainability elements indicating the need to move to af uture scenario of chemicali ndustrialp roduction denoted as "RE-driven chemistry", which can also provide ag reat opportunity for innovation and competitivity in chemical industry.I nt his Essay we discuss how it is realistic to conceive of RE-driven chemistry,w hich will be an on-incremental change to move to al ow-carbon economy,t hat is, with ad ecreasei nG HG emissions by up to 80 %. However,t his objective requires the fulfillment of two criteria: i) the use of RE-driven processes for the production of base raw materials, such as olefins,m ethanol, and ammonia,w hich are at the top of the chemical production value chain and ii)the development of RE-driven routes that simultaneously realize process and energy intensification, that is, which combine the use of RE in substitution of fossil fuels to significantly reducethe number of the process steps. Twospecific examples of using RE to realize novel conversion pathways are discussed: the direct synthesies of ammonia from N 2 andH 2 Oa nd that of acetic acid from CO 2 and H 2 O. They exemplify the above concept and the possibility of ar eductiono fo ver 80 % in GHG emissions. Some aspects of the production of olefins from renewable methanola re also discussed. Enabling this vision of an ew chemical industrial production based on the use of RE requires significant investment in new production technologies, because an on-incremental change in chemical industry-thedevelopment of newm aterials, reactors and processes( for example, based on the use of electrons and photons rather than heat as today)-is an ecessity.T hese novel technologiesw ill offer the opportunity to overcome the actual industrial process, by switching from largei ntegrated chemical plantst oad istributed modelo fp roduction with various sustainability benefits.

“…The photocatalytic reduction of CO 2 into hydrocarbons using solar energy, often referred to as artificial photosynthesis, is believed to be a potential and promising approach to solve both issues. [1][2][3][4][5] Since the reduction of CO 2 by a TiO 2 photocatalyst was reported by Inoue and Fujishima's group, [6] the photocatalytic reduction of CO 2 has attracted the attention of many researchers. The key to this process is to develop an efficient photocatalyst that can properly position the valence and conduction bands for the oxidation and reduction half-reactions of water and CO 2 , respectively.…”

Photocatalytic reduction of carbon dioxide (CO 2 ) into renewable hydrocarbon fuels using solar energy has gained much attention in the effort to conserve energy and enhance carbon cycling. This paper begins with a brief description of the basic concepts of the photocatalytic reduction of CO 2 , introduces some experimental challenges in the gas photoreaction system and provides a review of perovskite oxide semiconductor catalysts, including tantalates, niobates, titanates, zirconates and cerates, for use in the gas phase photoreduction of CO 2 . The prospects for the future research of CO 2 photoreduction are also presented.
