About us

Inorganic materials.
Sustainable possibilities.

The Functional Inorganic Materials and Photocatalysis Research Group (FIMP Group) explores inorganic and hybrid materials for a cleaner and more sustainable future. We connect synthesis and structural modification with environmental remediation, functional surfaces, chemical sensing, selective separation, and sustainable energy and chemical conversion.

Photocatalysis is central to our work, alongside piezo-photocatalysis, adsorption, and materials-based sensing. Digital Image Colorimetry (DIC) is a distinctive focus of our sensing research, translating colour responses into quantitative information. Led by Diana Rakhmawaty Eddy, with Muhamad Diki Permana as Senior Researcher, we investigate how material design enables these connected functions.

Green Synthesis of TiO₂ for Pharmaceutical Pollutant Degradation

We explore red spinach extract as a plant-based aid for synthesizing TiO₂ nanoparticles. Using paracetamol as a model pharmaceutical pollutant, this study examines how calcination changes material properties and improves photocatalytic performance under UV-B irradiation, connecting bio-assisted synthesis with environmental applications.

Multiphase TiO₂ Heterojunctions for Visible Light Photocatalysis

We combine anatase, rutile, and brookite TiO₂ with Ag₂O/Ag₂CO₃ through ultrasound-assisted synthesis. The resulting composite improves visible-light photocatalytic performance for metformin degradation. This work investigates how phase composition and heterojunction formation influence light absorption and charge separation in photocatalytic materials.

STRUCTURAL DEFECTS · ZnO/SiO₂

Structural Defects in ZnO Silica Photocatalysts

We investigate how ZnO loading and structural defects influence the performance of ZnO/SiO₂ composites. By connecting structural and optical properties with methylene blue removal, this study highlights the combined contributions of adsorption and photocatalysis and identifies an optimal composition among the materials tested.

ADSORPTION · MAGNETIC COMPOSITES

From Rice Husk Ash to Magnetic Adsorbents

We transform rice husk ash into magadiite–magnetite and carbon–magnetite composites for removing anionic surfactants from water. These materials combine adsorption capacity with magnetic recovery, linking agricultural waste utilization with functional material development and the practical separation of adsorbents after treatment.
