“…Thus the use of biomass for heating is decreasing, while the share of biomass for electricity and biofuel is getting larger. At the same time, there is a tendency in the publications about the environmental friendliness of bioenergy, in particular, its contribution to reducing the greenhouse effect [85,86].…”

Fundamental and applied research on renewable energy is actively supported for the development of world science and maintaining the energy independence and security of different countries. This section analyzes the publications of scientists from two countries-Ukraine and Poland-in the field of "thermoelectricity," "photoelectricity," and "bioenergy" to find regularities in each state and to determine the prospects for joint research. Ukraine and Poland share a common border and have similar climatic conditions and historical heritage, but Poland is a member of the EU, and its legislation in the field of renewable energy complies with the regulations of the European Community. Ukraine is making every effort to develop renewable energy. Comparison of the state of research in these countries is also an example of the analysis of the situation at the borders of EU countries and may answer questions related to sustainable development, the mass transition to renewable energy, and the refusal to use fossil fuels and nuclear power plants. The analysis is based on the results of data published in the international scientific databases Web of Science and Scopus. The most advanced areas of research in each country are identified, analyzed, and aimed at practical application.

“…The reactive sites of oxidized PVA, namely the carbonyl groups, serve as favorable locations for the formation of Schiff's bases through the condensation of amines or polyamines with these carbonyl groups. As a result, the modified PVA exhibits a tailorable structure with exceptional physical and chemical affinity for CO 2 [20,33–37] . The chemisorption of CO 2 gas by the amine groups leads to the formation of carbamate intermediates, which play a crucial role in determining the selectivity of CO 2 uptake.…”

The increasing concentration of carbon dioxide in the atmosphere poses significant challenges for its capture. Carbon dioxide emissions contribute substantially to the greenhouse effect, leading to detrimental effects on ecosystems and drastic climate change. In this study, we synthesized two polymeric Schiff's bases, by condensing partially oxidized polyvinyl alcohol (OPVA) with 1,2‐ethylene diamine and 1,6‐hexamethylene diamine. The formed Schiff's bases are abbreviated OPVA‐ED and OPVA‐HMD, respectively. OPVA was initially prepared through oxidation of polyvinyl alcohol using potassium permanganate. We investigated the potential of these Schiff's bases for CO2 adsorption. Structural elucidation of the Schiff's bases was conducted using Fourier transform infrared (FTIR), 1H nuclear magnetic resonance (NMR), and X‐ray diffraction (XRD) techniques. Thermogravimetric analysis (TGA) and gas adsorption experiments were employed to determine their physical properties. The capture and release of CO2 were evaluated at a temperature of 25 °C using these Schiff's bases as adsorbents. The findings indicate that OPVA‐ED exhibits superior CO2 adsorption capacity compared to OPVA‐HMD, with adsorption capacities of 0.22 mmol/g and 0.18 mmol/g at 15 bars for OPVA‐ED and OPVA‐HMD, respectively.

“…The carbonyl groups of oxidized PVA are considered to be the reactive sites for Schiff bases which are formed via the condensation of amines or polyamines with any carbonyl group. Thus, it offers a tailorable structure exhibiting extremely high physical and chemical a nity to CO 2 [20,[33][34][35][36][37]. Favorable chemisorption of CO 2 gas by amine groups results in the formation of carbamate intermediate, and it de nes the selectivity of CO 2 uptake.…”

The emission of carbon dioxide (CO2) is not only the primary cause of global warming but also results in severe environmental issues like an increase in Earth's average temperature. Herein, polymeric Schiff bases, OPVA-ED and OPVA-HMD, are synthesized via the condensation of partially oxidized polyviny1 alcohol (OPVA) with 1,2-ethylene diamine (ED) and 1,6-hexamethylene diamine (HMD), respectively, and their potential toward CO2 adsorption is investigated. Fourier transform infrared (FTIR), 1H nuclear magnetic resonance (NMR), and X-ray diffraction (XRD) are employed for the structural elucidation of these Schiff bases, and their physical properties are determined using thermogravimetric analysis (TGA), and gas adsorption experiments. The capture/release of CO2, using these Schiff bases as adsorbent, is assessed at 25°C. The results suggest that OPVA-ED is a more efficient adsorbent for CO2 as compared to OPVA-HMD, as the capacity of CO2 adsorption reaches up to 0.22 mmol/g and 0.18 mmol/g at 15 bars for OPVA-ED and OPVA-HMD, respectively.
