Indoor carbon dioxide (CO2) levels are often significantly higher than those outdoors, which is a growing health concern, particularly in urban areas where people spend over 80% of their time indoors. Traditional CO2 mitigation methods, such as ventilation and filtration, are becoming less effective as outdoor CO2 levels increase due to global warming. This study introduces a novel solution: cyanobacterial artificial plants that enhance indoor carbon capture while converting CO2 into oxygen (O2) and bioelectricity. These artificial plants use indoor light to drive photosynthesis, achieving a 90% reduction in indoor CO2 levels, from 5000 to 500 ppm—far surpassing the 10% reduction seen with natural plants. In addition to improving air quality, the system produces O2 and enough bioelectricity to power portable electronics. Each artificial leaf contains five biological solar cells that generate electricity during photosynthesis, with water and nutrients supplied through transpiration and capillary action, mimicking natural plant systems. The system generates an open circuit voltage of 2.7 V and a maximum power output of 140 µW. This decentralized approach offers a sustainable, energy‐efficient solution to indoor environmental challenges, providing improved air quality and renewable electricity amid rising global CO2 levels.

It is known that the temperature of crystallization during the synthesis of zeolite is one of the most important process parameters. However, during the research work on the synthesis of zeolite 13X and the introduction of this material into regular industrial production, it was noticed that the heating rate of the starting reaction suspension can have an equally important influence. This influence can be so pronounced that a difference of just a few minutes in reaching the crystallization temperature can make a significant difference in product quality, affect the presence of other phases in the crystal, or even determine the direction of zeolite crystallization. Therefore, the aim of this work was to show the influence of the heating rate on the quality of the obtained 13X zeolite powders. The obtained samples were analysed in terms of crystallinity (by X-ray diffraction), chemical composition, granulometry and specific surface area (by Brunauer-Emmett-Teller analysis), and regarding water and CO2 adsorption capacities. Additionally, scanning electron microscopy analysis of the samples showed the morphological characteristics of different 13X zeolite powders. The analysis results of the obtained powders confirmed the influence of the heating rate and helped to define the optimal synthesis parameters i.e. the initial temperature and heating time, that resulted in stable product quality.
