Innovating Everyday Chemicals with Green Chemistry: More Sustainable Lubricants, Solvents, and Fertilizers

Chemists across the industry and academia are driving innovation by integrating green chemistry and engineering principles into the design, manufacturing, and processes of chemicals. Join three recipients of the 2024 Green Chemistry Challenge Awards—a collaboration between the U.S. Environmental Protection Agency’s Office of Chemical Safety and Pollution Prevention and the American Chemical Society’s Green Chemistry Institute—as they share their impactful scientific achievements.

Supercritical Fluid Impregnation of Polyolefins with Organometallic Complexes for Fundamental Investigations of Catalytic C-C Bond Cracking

The challenge of plastic waste management has intensified globally due to the non-biodegradable nature and fossil-based origin of most plastics. This research presented explores a novel approach to plastic upcycling through ideal catalytic cracking, with a focus on greener reaction conditions, such as supercritical CO₂ (scCO₂) processing.

The CO2 Tree: The Potential for Carbon Dioxide Utilization Pathways (Poster)

Among the most active areas of chemistry research today is that of carbon dioxide utilization: an area of research that was viewed as futile and commercially impractical not so long ago due to the energetic stability of the CO2 molecule. The breakthroughs that largely began in earnest in the 1990s have accelerated and now make up a diverse and plentiful portfolio of technological and scientific advances and commercialized technologies.

Urea-Hydrogen Peroxide-Mediated C(sp2 )-H Bond Selenylation of Imidazoheteroarenes and Simple Activated Arenes

In recent decades there has been uprising interest in the medicinal properties of organoselenides. These ubiquitous structural have their wide applications in material sciences, in catalysis and modern organic transformations. Research studies have led to important discoveries regarding selective C–Se bond formation and in this context a notable approach is direct selenylation. In this regard, nitrogen- or oxygen-containing arenes with organoselenides have appeared as a very important class of molecules, with diverse applications in the biological sciences.

Developing Renewable Bioplastics from Bio-Derived Monomers

Enhancing the efficiency of material processing, utilization, and recycling is pivotal for advancing sustainability in modern society. The objective of this study is to create sustainable methods for converting non-food biomass into recyclable polymers. One key compound, 4,4'-biphenyldicarboxylic acid (BPDA), is used as an additive in copolymer production and as a blending agent to improve the properties of polyester. BPDA was synthesized through the oxidation of 4,4'-dimethylbiphenyl (DMBP), a compound that can be efficiently derived from biomass-sourced 2-methylfuran.

Preparation, Characterization and Application of Metallic and Bimetallic Nanocatalysts in the Synthesis of Potentially Bioactive Compounds, through Economic and Sustainable Processes

Supported metallic and bimetallic nanocatalysts were synthesized and characterized. They were employed in different steps of the synthesis of a variety of bioactive compounds, taken in place the high atom economy and the sustainability of the process. The recoverability and reusability of the nanocatalysts was studied. The nanocatalyst were used particularly in C-H activation reaction, through a cross dehydrogenative coupling reaction (CDC), to form new C-C and C-heteroatom bonds.
