Digitalization provides access to an integrated network of unexploited big data with potential benefits for society and the environment. The development smart systems connected internet things can generate unique opportunities strategically address challenges associated United Nations Sustainable Development Goals (SDGs) ensure equitable, environmentally sustainable, healthy society. This perspective describes that digitalization provide towards building sustainable future. Smart technologies are envisioned as game-changing tools, whereby their integration will benefit three essential elements food-water-energy nexus: (i) food production; (ii) clean safe potable water; (iii) green energy generation usage. It then discusses catalyze transition manufacturing practices enhance citizens' health wellbeing by providing digital care, particularly underserved communities. Finally, englobes a holistic view on how it contribute serious endangered planet biodiversity climate change.

Electrocatalytic Refinery for Sustainable Production of Fuels and Chemicals

Angewandte Chemie International Edition, Год журнала: 2021, Номер 60(36), С. 19572 - 19590

Опубликована: Фев. 19, 2021

Abstract Compared to modern fossil‐fuel‐based refineries, the emerging electrocatalytic refinery (e‐refinery) is a more sustainable and environmentally benign strategy convert renewable feedstocks energy sources into transportable fuels value‐added chemicals. A crucial step in conducting e‐refinery processes development of appropriate reactions optimal electrocatalysts for efficient cleavage formation chemical bonds. However, compared well‐studied primary (e.g., O 2 reduction, water splitting), mechanistic aspects materials design complex are yet be settled. To address this challenge, herein, we first present fundamentals heterogeneous electrocatalysis some reactions, then implement these establish framework by coupling situ generated intermediates (integrated reactions) or products (tandem reactions). We also set principles strategies efficiently manipulate reaction pathways.

Опубликована: Сен. 30, 2021

Reducing net emission The great majority of plastics in current use are sourced from fossil fuels, with additional fuels combusted to power their manufacture. Substantial research is focused on finding more sustainable building blocks for next-generation polymers. Meys et al . report a series life cycle analyses suggesting that even the varieties commercial monomers could potentially be manufactured and polymerized no greenhouse gas emissions. relies combining recycling plastic waste chemical reduction carbon dioxide captured incineration or derived biomass. —JSY

Progress and Perspectives in Photo‐ and Electrochemical‐Oxidation of Biomass for Sustainable Chemicals and Hydrogen Production

Advanced Energy Materials, Год журнала: 2021, Номер 11(43)

Опубликована: Июнь 17, 2021

Abstract Biomass is recognized as an ideal CO 2 neutral, abundant, and renewable resource substitute to fossil fuels. The rich proton content in most biomass derived materials, such ethanol, 5‐hydroxymethylfurfural (HMF) glycerol allows it be effective hydrogen carrier. oxidation derivatives, 2,5‐difurandicarboxylic acid from HMF, glyceric are valuable products used biodegradable polymers pharmaceuticals. Therefore, combining biomass‐derived compound at the anode evolution reaction cathode a electrolysis or photo‐reforming reactor would present promising strategy for coproducing high value chemicals with low energy consumption emissions. This review aims combine fundamental knowledge on photo electro‐assisted catalysis provide comprehensive understanding of general mechanisms different molecule oxidation. At same time, catalyst requirements recent advances various feedstock compounds also reviewed detail. Technoeconomic assessment life cycle analysis performed feedstocks assess relative benefits processes, finally critical prospects given challenges opportunities technology development meet sustainability requirement future global economy.

Sustainability Science: Toward a Synthesis

Annual Review of Environment and Resources, Год журнала: 2020, Номер 45(1), С. 331 - 386

Опубликована: Авг. 4, 2020

This review synthesizes diverse approaches that researchers have brought to bear on the challenge of sustainable development. We construct an integrated framework highlighting union set elements and relationships those shown be useful in explaining nature–society interactions multiple contexts. Compelling evidence has accumulated should viewed as a globally interconnected, complex adaptive system which heterogeneity, nonlinearity, innovation play formative roles. The long-term evolution cannot predicted but can understood partially guided through dynamic interventions. Research identified six capacities necessary support such interventions guiding development pathways toward sustainability. These are ( a) measure development, b) promote equity, c) adapt shocks surprises, d) transform into more pathways, e) link knowledge with action, f) devise governance arrangements allow people work together exercising other capacities.

Sustainable Li‐Ion Batteries: Chemistry and Recycling

Advanced Energy Materials, Год журнала: 2020, Номер 11(43)

Опубликована: Дек. 21, 2020

Abstract The commercial breakthrough of Li‐ion batteries (LIBs) in the 1990s irrevocably shaped today's energy storage landscape, but disposed represent a growing hazard to environment. One may initially assume that recycling processes are commendable technologies ensure counterbalance LIBs manufacturing. However, question remains whether current state‐of‐the‐art can be considered as green. This problem is due application toxic chemicals or situ generation harmful substances during process. Besides potential toxicity, solutions accompanied with intense consumption, causing carbon dioxide emissions, disagreement circular economy principles. review provides critical assessment both published research articles and patents derive broad picture on sustainability technologies. Although efficiency industrially applied exhibit high overall efficiency, their general process design generally based waste reduction downcycling. Contrariwise, sustainable should rely ensuring upcycling all materials toward zero minimized utilization. Current expected development presented, ranging from dismantling over components separation bioderived materials.
