Solution Overview
Problem
Existing nanocomposite materials suffer from inadequate multifunctionality, poor structural stability, limited scalability, and suboptimal performance in applications like environmental remediation, catalysis, and energy storage due to poor phase homogeneity, uncontrolled grain growth, and complex synthesis processes.
Innovation Solution

Engineering Contradiction Analysis
1Manufacturing precision
If conventional synthesis methods are used to prepare nanocomposite materials, then the manufacturing process is simple, but the phase homogeneity is poor and grain growth is uncontrolled
Solution Approach 1:
The synthesis process is divided into distinct sequential steps: sol-gel formation followed by controlled combustion. This segmentation allows each step to be optimized independently - the sol-gel step ensures homogeneous mixing at molecular level, while the combustion step provides controlled thermal treatment for phase formation, thereby achieving good phase homogeneity without requiring the entire process to be overly complex
Solution Approach 2:
The sol-gel process performs preliminary mixing and homogenization of metal precursors in solution before the combustion step. This preliminary action ensures that all phases are uniformly distributed at the molecular level before thermal treatment, which prevents uncontrolled grain growth and achieves homogeneous phase distribution in the final nanocomposite
2Stability of the object's composition
If high-temperature treatments are applied to improve material stability, then structural stability is enhanced, but energy consumption increases
Solution Approach 1:
The combustion synthesis method changes the thermal processing parameters by using a self-propagating exothermic reaction that reaches temperatures of 600-900°C locally but requires minimal external energy input. This parameter change allows achieving crystalline phase formation and structural stability without the continuous high energy input required by conventional sintering methods
Solution Approach 2:
The combustion process is self-sustaining once initiated, using the chemical energy stored in the organic fuel (citric acid, urea, or glycine) to provide the necessary heat for phase formation and crystallization. This self-service mechanism eliminates the need for continuous external heating, thereby reducing overall energy consumption while achieving stable crystalline structures
3Reliability
If complex processing steps are used to achieve desired nanocomposite properties, then material performance is improved, but production cost increases
Solution Approach 1:
Multiple functions are merged into a single combustion synthesis step: phase formation, particle size control, morphology development, and compositional homogenization all occur simultaneously during the self-propagating combustion reaction. This merging eliminates the need for multiple separate processing steps (such as separate sintering, milling, and characterization iterations), thereby reducing production cost while maintaining high material performance
Solution Approach 2:
By changing the combustion parameters (fuel-to-oxidizer ratio, heating rate, atmosphere), the method can control particle size, phase composition, and morphology in a single step. This parameter control capability replaces multiple iterative processing steps, reducing both time and cost while achieving the desired nanocomposite properties
