What SajTom Light Future is?

SajTom Light Future Ltd. is a legal entity founded on June 1st 2015 by two young scientists: Dr Szymon Wojtyla - Management Director and Dr Tomasz Baran - Chief Operating Officer. Research and development in the field of chemical sciences is the statutory aim of the company. Currently, the activity of the SajTom Light Future focuses on the development and commercialization of photocatalytic solutions and semiconductor technology. SajTom Light Future Ltd. provides a means for a further developing of photocatalytic products, that were studied during basic research. Patents pending and scientific papers in top scientific journals of international scope, such as American Chemical Society journals are the effect of our scientific works. The company is a member of the business club Startupitalia. Directors of the company belong to the prestigious scientific societies such as Polish Chemical Society and Italian Chemical Society as well as Editorial Bord of the journal published by the American Research Publications. SajTom Light Future strives to be an attractive partner for industry and investors going towards commerzialization of novel innovative products.

Our goals

Identification of problem
Proof of concept

The world is full of challenges. Life. Industry. Inspiration can be found anywhere.


High quality research carried out together with scientists from academic research centers lead to new knowledge development as well as novel solutions for industry.

Materials scale-up
System prototype demonstration in an operational environment

Based on results from prototype demonstration in a relevant environment We prepare and study a prototype near or at planned operational system.

Patent pending

Our scientific results can be published or patented. Such intellectual property can be shared with industry to implementate a novel technology.

Board of directors

Dr Szymon Wojtyla

Managing director

Chemist. Graduated from Jagiellonian University in Cracow. 29 years old. Interests: the development of novel techniques for semiconductors study, photocatalysis, processes of small molecules activation, the transfer of energy and charges.

Dr Tomasz Baran

Chief Operating Officer

Doctor of chemistry. Graduated from Jagiellonian University in Cracow (Pl) and University of Bari (It). 29 years old. Interests: photocatalysis and photoelectrocatalysis, conversion of energy to fuels, synchrotron techniques, novel semiconducting materials


Photocatalysis is a promising science for future applications which combines the topics of materials science, nanotechnology, energy research, environmental science, photonics and chemical analysis. The motivation for the current interest in this topic stems from the challenges science and society face from climate change and energy supply. Already, photocatalysis is commercially used to passively degrade pollutants. Another goal is to produce useful chemical products such as hydrogen or methane and other solar fuels. It is a simple, renewable, clean and cost effective technology which will play an ever more important role as the science progresses. Photosynthesis is one of the most famous chemical reactions and it is our photocatalysis model from nature. Plants use sunlight as their energy source to convert carbon dioxide to useful sugars. Scientists hope to replicate this reaction in the lab due to suitable photocatalyst materials. Our company investigates new materials and their properties for enhancing the rate of photocatalytic process. We are looking at metal and non-metal systems, nanomaterials and hybrid materials. There is also valuable fundamental science which needs to be extended for these typical materials and everyday reactions to open up new fields of knowledge and opportunities.

Areas of interest (areas of work):

  • Photocatalytic degradation of pollutants
  • Photocatalytic purification of water, surface and air
  • Photocatalytic filters for removing of volatile organic compounds
  • Optoelectronic materials
  • Photocatalytic biopolymers
  • Photocatalytic textiles

We are ready for new ideas, new applications and new projects

    Photocatalytic filter for 3D printer

    Together with company 3D Kreator we studied the risk of 3D printing related to ultrathin particles and VOCs emission. We worked on photocatalytic filtration of such pollutants: novel photocatalyst, supports for materials, geometry of photocatalytic filter etc. This resulted in development of the SYNE technology development – the filtration system based on photocatalysis designed for printers. The commercially available printer Accura Genius3D is the first printer in the World equipped with photocatalytic filter.
